I think Ron's point is that with this set of terms (i.e. 1st/2nd corner refers to the person rather than the position), if we're in an improper context, we've basically circled back around to labeling the roles, only these role labels seem unideal because they have lots of syllables and sound relatively similar. At the point at which we're talking about "first corner" and "second corner", isn't it less of a mouthful, easier to understand, and easier for experienced dancers to convert into terms they understand to have a set of terms like jets[gems]/rubies or larks/ravens?
