opinion: Justice BREYERdelivered the opinion of the Court.
  Ordinarily, a federal litigant who is too poor to pay court fees may proceed in forma pauperis. This means that the litigant may commence a civil action without prepaying fees or paying certain expenses. See 28 U.S.C. § 1915. But a special "three strikes" provision prevents a court from affording in forma pauperisstatus where the litigant is a prisoner and he or she "has, on 3 or more prior occasions, while incarcerated ..., brought an action or appeal in a court of the United States that was dismissed on the grounds that it is frivolous, malicious, or fails to state a claim upon which relief may be granted." § 1915(g).
  Prior to this litigation, a Federal District Court had dismissed on those grounds three actions brought by a state prisoner. While the third dismissal was pending on appeal, the prisoner sought to bring several additional actions in the federal courts. The question before us is whether the prisoner may litigate his new actions in forma pauperis. Where an appeals court has not yet decided whether a prior dismissal is legally proper, should courts count, or should they ignore, that dismissal when calculating how many qualifying dismissals the litigant has suffered?
  We conclude that the courts must count the dismissal even though it remains pending on appeal. The litigant here has accumulated three prior dismissals on statutorily enumerated grounds. Consequently, a court may not afford him in forma pauperisstatus with respect to his additional civil actions.

  Congress first enacted an in forma pauperisstatute in 1892. See Act of July 20, ch. 209, 27 Stat. 252. Congress recognized that "no citizen sh[ould] be denied an opportunity to commence, prosecute, or defend an action, civil or criminal, in any court of the United States, solely because his poverty makes it impossible for him to pay or secure the costs." Adkins v. E.I. DuPont de Nemours & Co.,335 U.S. 331, 342, 69 S.Ct. 85, 93 L.Ed. 43 (1948)(internal quotation marks omitted). It therefore permitted a citizen to "commence and prosecute to conclusion any such ... action without being required to prepay fees or costs, or give security therefor before or after bringing suit." § 1, 27 Stat. 252. The current statute permits an individual to litigate a federal action in forma pauperisif the individual files an affidavit stating, among other things, that he or she is unable to prepay fees "or give security therefor." 28 U.S.C. § 1915(a)(1).
  Even in 1892, "Congress recognized ... that a litigant whose filing fees and court costs are assumed by the public, unlike a paying litigant, lacks an economic incentive to refrain from filing frivolous, malicious, or repetitive lawsuits." Neitzke v. Williams,490 U.S. 319, 324, 109 S.Ct. 1827, 104 L.Ed.2d 338 (1989). And as the years passed, Congress came to see that prisoner suits in particular represented a disproportionate share of federal filings. Jones v. Bock,549 U.S. 199, 202-203, 127 S.Ct. 910, 166 L.Ed.2d 798 (2007). It responded by "enact[ing] a variety of reforms designed to filter out the bad claims [filed by prisoners] and facilitate consideration of the good." Id.,at 204, 127 S.Ct. 910. Among those reforms was the "three strikes" rule here at issue. The rule, which applies to in forma pauperis status, reads in its entirety as follows:
  "In no event shall a prisoner bring a civil action or appeal a judgment in a civil action or proceeding [in forma pauperis] if the prisoner has, on 3 or more prior occasions, while incarcerated or detained in any facility, brought an action or appeal in a court of the United States that was dismissed on the grounds that it is frivolous, malicious, or fails to state a claim upon which relief may be granted, unless the prisoner is under imminent danger of serious physical injury." § 1915(g).

  The petitioner, André Lee Coleman, is incarcerated at the Baraga Correctional Facility in Michigan. By 2010, three federal lawsuits filed by Coleman during his incarceration had been dismissed as frivolous (or on other grounds enumerated in § 1915(g)). Nonetheless, when Coleman filed four new federal lawsuits between April 2010 and January 2011, he moved to proceed in forma pauperisin each. He denied that his third dismissed lawsuit counted as a strike under § 1915(g). That is because he had appealed the dismissal, and the appeals court had not yet ruled. Thus, in Coleman's view, he had fewer than three qualifying dismissals, and was eligible for in forma pauperisstatus under the statute.
  The District Court rejected Coleman's argument. It held that "a dismissal counts as a strike even if it is pending on appeal at the time that the plaintiff files his new action." No. 10-cv-337 (WD Mich., Apr. 12, 2011), App. to Pet. for Cert. 21a, 24a. It thus refused to permit Coleman to proceed in forma pauperisin any of his four suits.
  On appeal, a divided panel of the Sixth Circuit agreed with the District Court. 733 F.3d 175 (2013). It resolved the four cases using slightly different procedures. In one of the four cases, the Sixth Circuit affirmed the District Court's judgment. In the remaining three cases, it denied Coleman's request to proceed in forma pauperison appeal. It subsequently dismissed the three cases for want of prosecution after Coleman failed to pay the appellate filing fees.
  In contrast to the Sixth Circuit, the vast majority of the other Courts of Appeals have held that a prior dismissal on a statutorily enumerated ground does not count as a strike while an appeal of that dismissal remains pending. See Henslee v. Keller,681 F.3d 538, 541 (C.A.4 2012)(listing, and joining, courts that have adopted the majority view). In light of the division of opinion among the Circuits, we granted Coleman's petition for certiorari.

  In our view, the Sixth Circuit majority correctly applied § 1915(g). A prior dismissal on a statutorily enumerated ground counts as a strike even if the dismissal is the subject of an appeal. That, after all, is what the statute literally says. The "three strikes" provision applies where a prisoner "has, on 3 or more prior occasions ... brought an action or appeal ... that was dismissedon" certain grounds. § 1915(g)(emphasis added). Coleman believes that we should read the statute as if it referred to an "affirmed dismissal," as if it considered a trial court dismissal to be provisional, or as if it meant that a dismissal falls within the statute's scope only when the litigant has no further chance to secure a reversal. But the statute itself says none of these things.
  Instead, the statute refers to whether an action or appeal "was dismissed." § 1915(g). The linguistic term "dismiss," taken alone, does not normally include subsequent appellate activity. See, e.g., Heintz v. Jenkins,514 U.S. 291, 294, 115 S.Ct. 1489, 131 L.Ed.2d 395 (1995)("[T]he District Court dismissed [the] lawsuit for failure to state a claim.... However, the Court of Appeals for the Seventh Circuit reversed the District Court's judgment"); Gray v. Netherland,518 U.S. 152, 158, 116 S.Ct. 2074, 135 L.Ed.2d 457 (1996)("The Suffolk Circuit Court dismissed petitioner's state petition for a writ of habeas corpus. The Virginia Supreme Court affirmed the dismissal"). Indeed, § 1915itself describes dismissal as an action taken by a single court, not as a sequence of events involving multiple courts. See § 1915(e)(2)("[T]he court shall dismiss the case at any time if the courtdetermines that-(A) the allegation of poverty is untrue; or (B) the action or appeal-(i) is frivolous or malicious; [or] (ii) fails to state a claim on which relief may be granted" (emphasis added)).
  Coleman insists that § 1915(g)is not so clear. Even if the term "dismissed" is unambiguous, contends Coleman, the phrase "prior occasions" creates ambiguity. Coleman observes that the phrase " 'may refer to a single moment or to a continuing event: to an appeal, independent of the underlying action, or to the continuing claim, inclusive of both the action and its appeal.' " Brief for Petitioner 17 (quoting Henslee, supra,at 542). Coleman believes that a "prior occasion" in the context of § 1915(g)may therefore include both a dismissal on an enumerated ground and any subsequent appeal.
  We find it difficult to agree. Linguistically speaking, we see nothing about the phrase "prior occasions" that would transform a dismissal into a dismissal-plus-appellate-review. An "occasion" is "a particular occurrence," a "happening," or an "incident." Webster's Third New International Dictionary 1560 (3d ed. 1993). And the statute provides the content of that occurrence, happening, or incident: It is an instance in which a "prisoner has ... brought an action or appeal in a court of the United States that was dismissed on" statutorily enumerated grounds. § 1915(g). Under the plain language of the statute, when Coleman filed the suits at issue here, he had already experienced three such "prior occasions."
  Our literal reading of the phrases "prior occasions" and "was dismissed" is consistent with the statute's discussion of actions and appeals. The in forma pauperisstatute repeatedly treats the trial and appellate stages of litigation as distinct. See §§ 1915(a)(2), (a)(3), (b)(1), (e)(2), (g). Related provisions reflect a congressional focus upon trial court dismissal as an important separate element of the statutory scheme. See § 1915A (requiring a district court to screen certain prisoner complaints "as soon as practicable" and to dismiss any portion of the complaint that "is frivolous, malicious, or fails to state a claim upon which relief may be granted"); 42 U.S.C. § 1997e(c)(1)(similar). We have found nothing in these provisions indicating that Congress considered a trial court dismissal and an appellate court decision as if they were a single entity-or that Congress intended the former to take effect only when affirmed by the latter.
  Our literal reading of the "three strikes" provision also is supported by the way in which the law ordinarily treats trial court judgments. Unless a court issues a stay, a trial court's judgment (say, dismissing a case) normally takes effect despite a pending appeal. See Fed. Rule Civ. Proc. 62; Fed. Rule App. Proc. 8(a). And a judgment's preclusive effect is generally immediate, notwithstanding any appeal. See Clay v. United States,537 U.S. 522, 527, 123 S.Ct. 1072, 155 L.Ed.2d 88 (2003)("Typically, a federal judgment becomes final for ... claim preclusion purposes when the district court disassociates itself from the case, leaving nothing to be done at the court of first instance save execution of the judgment"). The ordinary rules of civil procedure thus provide additional support for our interpretation of the statute. See Jones,549 U.S., at 211-216, 127 S.Ct. 910(applying the ordinary rules of civil procedure where the procedural requirements for prison litigation do not call for an alternative).
  Finally, the statute's purpose favors our interpretation. The "three strikes" provision was "designed to filter out the bad claims and facilitate consideration of the good." Id.,at 204, 127 S.Ct. 910. To refuse to count a prior dismissal because of a pending appeal would produce a leaky filter. Appeals take time. During that time, a prisoner could file many lawsuits, including additional lawsuits that are frivolous, malicious, or fail to state a claim upon which relief may be granted. Indeed, Coleman filed these four cases after he suffered his third qualifying dismissal, in October 2009, and before the affirmance of that order, in March 2011.
  We recognize that our interpretation of the statute may create a different risk: An erroneous trial court dismissal might wrongly deprive a prisoner of in forma pauperisstatus with respect to lawsuits filed after a dismissal but before its reversal on appeal. But that risk does not seem great. For one thing, the Solicitor General informs us that he has been able to identify only two instances in which a Court of Appeals has reversed a District Court's issuance of a third strike. Brief for United States as Amicus Curiae22, n. 5. For another, where a court of appeals reverses a third strike, in some instances the prisoner will be able to refile his or her lawsuit after the reversal, seeking in forma pauperisstatus at that time. Further, if the statute of limitations governing that lawsuit has run out before the court of appeals reverses the third strike, the Solicitor General assures us that prisoners will find relief in Federal Rule of Civil Procedure 60(b). According to the Solicitor General, a prisoner may move to reopen his or her interim lawsuits (reinstating the cases as of the dates originally filed) and may then seek in forma pauperisstatus anew. In any event, we believe our interpretation of the statute hews more closely to its meaning and objective than does Coleman's alternative.
  B
  Coleman makes an additional argument. He poses a hypothetical: What if this case had involved an attempt to appeal from the trial court's dismissal of his third complaint instead of an attempt to file several additional complaints? If the dismissal were counted as his third strike, Coleman asserts, he would lose the ability to appeal in forma pauperis from that strike itself. He believes that this result, which potentially could deprive him of appellate review, would be unfair. He further believes that it would be such a departure from the federal courts' normal appellate practice that Congress could not possibly have intended it.
  The Solicitor General, while subscribing to our interpretation of the statute, supports Coleman on this point. The Solicitor General says that we can and should read the statute to afford a prisoner in forma pauperisstatus with respect to an appeal from a thirdqualifying dismissal-even if it does not allow a prisoner to file a fourth case during that time. He believes that the statute, in referring to dismissals "on 3 or more prior occasions," 28 U.S.C. § 1915(g)(emphasis added), means that a trial court dismissal qualifies as a strike only if it occurred in a prior, different,lawsuit.
  We need not, and do not, now decide whether the Solicitor General's interpretation (or some other interpretation with the same result) is correct. That is because Coleman is not here appealing from a third-strike trial-court dismissal. He is appealing from the denial of in forma pauperisstatus with respect to several separate suits filed after the trial court dismissed his earlier third-strike suit. With respect to those suits, the earlier dismissals certainly took place on "prior occasions." If and when the situation that Coleman hypothesizes does arise, the courts can consider the problem in context.
  * * *
  For the reasons stated, we hold that a prisoner who has accumulated three prior qualifying dismissals under § 1915(g)may not file an additional suit in forma pauperiswhile his appeal of one such dismissal is pending. The judgments of the Court of Appeals are
  Affirmed.
