Morphology

thienyl = thiophene (opaque) = thien + yl

Formed by adding the chemical suffix '-yl' to the heterocycle name 'thiophene'; the relation is technical and not transparent to average learners.

Etymology

Thienyl comes from thiophene and the ending -yl, where thio- means 'sulfur' and -yl names a 'group' in chemistry, as in ethyl. So a thienyl is the 'group' made from thiophene often by taking one hydrogen and used as a part in other molecules.
