Various kinds of wordplay can be devised using deletions: the APRICOT contains a PIT, household GARBAGE yields GARAGE sales. The May 1967 Word Ways featured Tom Pulliam's synonymic deletions: INDOLENT contains IDLE, to DECLINE is to DIE. This article features a special class of deletions -- those in which the even letters of a word are struck out, leaving another word.
