Why “interosculate” is a great word
To share characteristics at a boundary, or to connect by touching like two mouths meeting. From Latin inter- ("between") and osculare, from osculum ("little mouth, kiss"), thus "to kiss between"; the earliest known use is from 1882, in Ogilvie's Imperial Dictionary. Unlike "intersect," which implies a crisp crossing of paths, or "intermingle," which suggests a general diffusion, to interosculate is to blur a line while preserving the essence of what lies on either side. It is the hybrid zone where two distinct species of tree exchange pollen and produce a fertile, intermediate form; it is the moment in conversation when two separate thoughts brush against one another and briefly become a single, richer idea; it is the quiet, permeable border where one ecosystem yields to another, sharing nutrients and decay. A recognition that connection often requires a softening of edges, not their erasure.
