cross-threading alert
from a bexter link in the acronyms thread:

Some lexicographic wit coined a term for what’s ­happened to laser, radar, and their ilk: they’ve become ­anacronyms, a ­neologism that smooshes the sounds (and the meanings) of acronym and anachronism. The product of smooshing two words together, by the way, is a portmanteau.

When an acronym becomes an anacronym, funny things can happen to it. For one, people sometimes start saying the acronym coupled with the verbalization of one of its constituent elements. Hence in ”SCSI interface,” the word ”interface” is completely redundant, because that’s what the ”I” is for.
