14-letter words containing e, c, t, a, s
- eta conversion — (theory) In lambda-calculus, the eta conversion rule states \ x . f x <--> f provided x does not occur as a free variable in f and f is a function. Left to right is eta reduction, right to left is eta abstraction (or eta expansion). This conversion is only valid if bottom and \ x . bottom are equivalent in all contexts. They are certainly equivalent when applied to some argument - they both fail to terminate. If we are allowed to force the evaluation of an expression in any other way, e.g. using seq in Miranda or returning a function as the overall result of a program, then bottom and \ x . bottom will not be equivalent. See also observational equivalence, reduction.

- hash character — (character) "#", ASCII character 35. Common names: number sign; pound; pound sign; hash; sharp; crunch; hex; INTERCAL: mesh. Rare: grid; crosshatch; octothorpe; flash; ITU-T: square, pig-pen; tictactoe; scratchmark; thud; thump; splat. The pronunciation of "#" as "pound" is common in the US but a bad idea; Commonwealth Hackish has its own, rather more apposite use of "pound sign" (confusingly, on British keyboards the pound graphic happens to replace "#"; thus Britishers sometimes call "#" on a US-ASCII keyboard "pound", compounding the American error). The US usage derives from an old-fashioned commercial practice of using a "#" suffix to tag pound weights on bills of lading. The character is usually pronounced "hash" outside the US. The name "octothorpe" was made up by a Bell Labs supervisor, Don Macpherson.
