When we think, we often try to put our ideas into words that can be shared with others. That's where the phrase "develops a thought" comes in. However, there are many alternative phrases we can use to express this same idea. We might say, "expands on an idea," "fleshes out a concept," "builds upon a notion," or "elaborates on a theory." Whichever phrase we choose, the goal is the same: to take a germ of an idea and turn it into something more complete and robust. So the next time you find yourself "developing a thought," consider trying out one of these alternative phrases instead.
