Morphology

lectin = lect + in

Formed from the combining form 'lect-' plus the protein-forming suffix '-in', but the root is not a standalone English word and the specific biochemical meaning is not derivable by an average B1 learner from the parts.

Etymology

The word lectin comes from a Latin root lect- meaning 'to choose', the same root you find in select. So a lectin is a protein that 'chooses' and sticks to certain sugars, which helps you remember that it only attaches to some sugars and not others.
