Morphology

cresyl = cresol (semi-transparent) = cresol + yl

The noun denotes the radical/group formed from 'cresol' with the suffix '-yl'; this is transparent to those who know chemical morphology but not to typical learners.

Etymology

The word cresyl names a chemical group and comes from the name cresol, the molecule it is based on. So a cresyl group is the part of a molecule that is 'derived from' cresol, and chemists use the name to show that connection.
