Q. I’m editing a manuscript that uses the terms over-commitment and under-commitment, sometimes in the same paragraph. The writers have hyphenated both terms. Does it look inconsistent to make the first term one word and the second term two words? Would it be less jarring to hyphenate both, as they have done? I’m fine with overcommitment as one word and under commitment as two, but I need some backing up so I can remove the unnecessary hyphens.

A. Chicago style closes up both terms. Under commitment looks odd; it makes under look like a preposition (as in under consideration). It would be best to either close up both or hyphenate both.
