Surface Forms

Morphology

cationic = cation (transparent) = cation + ic

The adjective is formed by adding the productive suffix '-ic' to the noun 'cation', yielding 'relating to cations'.

Etymology

Cationic comes from Greek parts cata- meaning 'down' and ion meaning 'going', because early scientists saw positive ions 'go down' toward the negative side in experiments. So cationic describes something that has or relates to positive, or positively charged, 'ions'.
