Homoconcominym
Two words or phrases sound like two or more other words or phrases that form a familiar set. Examples: hied, hare (“neither hide nor hair”); or hart, sole (“heart and soul”); or read, wight, blew (“red, white, and blue”). Unlike most flats, homoconcominym bases need not have dictionary nature.
The homoconcominym is similar to a homonym group, but for the homoconcominym there is no expectation that the group be clued, and the notion of a “group” is more flexible.
