In ancient Greek poetry and Latin poetry, an iambic trimeter is a quantitative meter, in which a line consists of three iambic "metra". Each "metron" consists of the pattern | x – u – |, where "–" represents a long syllable, "u" a short one, and "x" an "anceps" (either long or short). Resolutions were common, especially in the first two metra of the line, so that any long or "anceps" syllable except the last could be replaced by two short syllables (see for example Euripides#Chronology), making a total of 13 or more syllables. It is the most common meter used for the spoken parts (as opposed to the sung parts) of Ancient Greek tragedy, comedy, and satyr plays. It is also common in iambus or 'blame poetry', although it is not the only meter for that genre.
