Problem:
The verb snowblow, formed from the noun snowblower, is relatively new and occurs relatively infrequently in writing. Which of the following options seems to be the most commonly used past tense form of the verb: snowblowed, snowblew, snow-blowed, or snow-blew? (Hint: Because these words will be relatively uncommon, it would be helpful to use an especially large corpus. I suggest the iWeb Corpus.)
