Morphology
xanthine = xanth + ine
Although historically built from the combining form 'xanth-' (yellow) + the chemical suffix '-ine', the combining form is not a standalone English word and the resulting chemical name is technical, so an average B1 learner cannot derive the meaning from the parts.
Etymology
Xanthine comes from the Greek root xanth- meaning 'yellow' and the chemical ending -ine. So, even though xanthine itself is often colorless, its name shows it belongs to a group of related chemicals that were noticed for a yellow colour.
