Morphology

theine = tea (semi-transparent) = the + ine

The form links clearly to 'tea' and the chemical suffix '-ine', but the specialized chemical naming and the historical notion of a distinct compound make the relation only partially obvious to average learners.

Etymology

The word theine comes from tea and the chemical ending -ine, and it was used to name the part of the drink that 'wakes you up', just like caffeine in coffee. So, theine refers to the caffeine found in tea.
