Sorry, had problems logging on and then got swamped with school. I knew I should have left someone else to figure out the category so I wouldn't have to come up with a list!

Here it is:

not short, not as much

punch, tell on, comfort

dessert, definite article, impale, donkey

exhibition, weep, pronoun, we

sculptural toy

river horse, box, assuage

expire, exclamation, a girl's name, leg joints

song, eastern grain, instructed, boring

fur, holder, lamp, throw

a hatchet, not her, not a woman, confront
