forkhead singular
forkheads plural

Morphology

forkhead = fork + head (semi-transparent) = fork + head

The form is a clear compound of 'fork' + 'head', but the technical biological meaning (a protein domain/family name) is specialized and not directly inferable by a general learner from the component meanings.

Etymology

Forkhead comes from the simple words fork and head, with 'fork' meaning a split or prong. It was first used in fruit flies because mutants had a 'forked' head, and the protein has a head-like part that helps control genes as animals develop. So a forkhead domain is the part of a protein that helps turn genes on and off during development.
