Morphology

gliadin = gliad + in

The element 'gliad' is an obscure combining form (not a standalone English word) and while '-in' is a protein-forming suffix, this composition is not predictable for average learners from known English vocabulary.

Etymology

Gliadin comes from the Greek root glia meaning 'glue' plus the common protein ending -in, and it is closely linked to gluten. It is a protein in wheat, so you can think of it as the 'glue' that makes dough stretchy, which explains why it matters for people with celiac disease.
