[Q]: Question: What word means to make something obsolete? For example, the automobile made the horse and buggy obsolete. How would the word obsolete be applied as a verb? obsoleted The automobile obsoleted the horse and buggy. bleech. made obsolete The automobile made obsolete the horse and buggy. Not bad, but there's room for improvement. EDIT: I'm looking for a verb that has an edge; that captures the upheaval and aggressiveness involved in displacing a product or industry. Killed is a bit strong. killed The automobile killed the horse and buggy. A bit overstated. ran out of business The automobile ran the horse and buggy out of business marginally better, but still not good. disrupted the automobile disrupted the horse and buggy Better applied to an industry, like so the automobile disrupted the transportation industry in the early 20th century; particularly the horse and buggy. Wordy. smashed The automobile smashed the horse and buggy. More along the lines of what I seek, but a bit improper. XXX The automobile XXX the horse and buggy. What verb fits best here? 
Answer: supplanted, succeeded, undermined, unseated, usurped, ejected, ousted.
[A]: no


[Q]: Question: If there are an odd number of competitors at any stage of a single-elimination tournament, one player is excused from play and continues on as if he had defeated his (nonexistent) opponent. This is called "getting a by". Or "getting a bye". Who knows, maybe it's even "getting a buy", although I doubt it. My dictionary lists by as meaning "pass" in card-games, so that suggests that spelling. On the other hand, the image of the referee looking from the single player, to the empty and undefended far side of the field, and then back to the player, shrugging, and saying "Bye", is too strong to easily discard. Like other parts of the anatomy, everyone's got an opinion. I'm looking for a cite. 
Answer: Here's what you get: bye 1 |bi| noun 1 the transfer of a competitor directly to the next round of a competition in the absence of an assigned opponent. [From the New Oxford American Dictionary.].
[A]: yes


[Q]: Question: In computer programming, when you append a "string" to another, you add it to the end of the former string. E.g. String string1 = "abcd"; String string2 = "efgh"; Appending the two strings would give "abcdefgh" But what if I wanted to add string2 before string1 to have the result: "efghabcd" What would be a good name for that that reverse operation? What is the opposite of "append"? 
Answer: Prepend, insert, pre-attach. Some programming languages have additional functions that can add strings in various positions, including the start of another string. For example: slice, push, at.
[A]:
no
