Surface Forms

caffeine singular
caffeines plural

Morphology

caffeine = cafe (semi-transparent) = caffein + e + ine

The form ultimately derives from 'café' (coffee) plus the chemical naming suffix '-ine', so the link to coffee is perceptible but the suffix is a technical/borrowed marker and the exact form is altered.

Etymology

Caffeine comes from the word for coffee plus the chemical ending -ine, so it literally means 'coffee substance'. This is why caffeine is the bitter, stimulating part found in coffee, tea, and many soft drinks.
