Pronunciation: (ûrs, ârs), [key]
Emergency Radio Service. Also,E.R.S.
a semantically empty suffix that creates informal variations of more neutral nouns and adjectives by processes of truncation identical to those of -er 7 (champers; preggers; starkers); unlike that suffix, however, -ers is apparently productive, and words formed with it do not appear to belong to a restricted linguistic register, as university slang.
