A linking compound is a composite word formed by joining two elements that emphasize connection, relationship, or transition between the constituent parts. In poetry, linking compounds function as linguistic bridges that unite disparate concepts, images, or qualities into single expressive units that foreground the relational dimension. These formations allow poets to articulate connections efficiently, create metaphorical relationships through juxtaposition, or achieve compression by binding meanings that might otherwise require multiple words. Linking compounds make visible the synthesizing activity central to poetic thinking and expression.

A Linking compound joins words to suggest continuous action or blended identity (e.g., "windborne")—creates fluidity and fusion in poetic diction.
