Did you know?

Slew appeared as an American colloquialism in the early 19th century. Its origins are unclear, but it is perhaps taken from the Irish slua, a descendant of Old Irish slúag, meaning "army," "host," or "throng." Slew has several homographs (words that are spelled alike but different in meaning, derivation, or pronunciation) in English. These include: slew as the past tense of the verb slay; slew as a spelling variant of slough, a word which is also commonly pronounced \SLOO\ and which means "swamp," "an inlet on a river," or "a creek in a marsh or tide flat"; and the verb slew, meaning "to turn, veer, or skid."
