»modem

After reading Arnold Zwicky's latest entry in the Language Log, I discovered that I did not know the origin of the word modem, which he lists along with radar and scuba as acronyms that have entered the language as common, rather than proper, nouns.
modem is a portmanteau, the sort of word that delighted Humpty Dumpty: from modulate and demodulate, it describes the function of the instrument which sends digital signals over analogue carriers. The genial egg describes the concept of linguistic portmanteau while explaining the poem Jabberwocky (one of the few English poems I have committed to memory).

I supose that modem will now apply for extra wages.
