think through think (something) through to consider something carefully, esp. before making an important decision. We can't afford a mistake, so think things through and make sure you have everything ready. You should think through all these questions before you send your proposal to a publisher. Usage notes: also used in the form think out something: He's trying to think out all the options available before deciding on one. I totally rewrote the entries for "think out/through" and added "think over"--SL, 2/03 |
