Alright, continuing with recently finished projects, here are five worksheets on the homophones rack and wrack used, in both cases, as nouns and verbs. Both of these words are complicated in their usage, and in fact rarely used in their full range of meanings–which is probably why I never finished this several years ago when I was developing a series of homophone worksheet.
In any case, in these worksheets, both words are used as nouns and verbs. Rack, as a verb, is used both intransitively and transitively; wrack as a verb is used only transitively and really has only one meaning: “to utterly ruin : WRECK.”
