Last night, I used the phrase “strewn about,” and it got me to wondering: WTF is the present tense of “strewn?” Strew? As it turns out, it is: To strew. But nobody ever uses it in any form other than “strewn,” at least not that I’ve ever heard.

And that got me to wondering: Are there any other verbs that are commonly used, but only in a past-tense or other non-root form?
