Word Origin and History for -gram
suffix from telegram (1852), first abstracted 1979 (in Gorillagram, a proprietary name in U.S.), and put to wide use in forming new words, such as stripagram (1981). The construction violates Greek grammar, as an adverb could not properly form part of a compound noun.
