Morphology

phosphatase = phosphate (semi-transparent) = phosphate + ase

Formed from 'phosphate' + the biochemical suffix '-ase' meaning an enzyme acting on phosphates; the meaning is systematic but '-ase' is specialized and may be unfamiliar to general learners.

Etymology

Phosphatase comes from phosphate, the chemical 'phosphate' group, and the enzyme ending -ase, as in lactase, which means 'an enzyme that acts on' something. So a phosphatase is an enzyme that 'removes' a phosphate group from a molecule, which explains its role in many cell reactions.
