ALOTT5MA GRAMMAR RODEO: BONUS WEDNESDAY EDITION: A profile of popular British historian Lucy Worsley in the current New Yorker contains the following sentence:
To learn about fifteenth-century hygiene, she forwent showers for a week and brushed her teeth with powdered cuttlefish bone.
Forwent? For real? Google had 137K hits for "forwent" (and 120K for "forewent"), 143K for "foregoed," and a whopping 967K for "chose to forego," which I'd employ rather than either of the prior formulations. (
Ngram prefers forwent.)
