Morphology

acidity = acid (transparent) = acid + ity

Formed directly from 'acid' + suffix '-ity' meaning 'the quality or state of being acidic', which is straightforward for learners.

Etymology

Acidity comes from the word acid, which comes from Latin acidus meaning 'sour'. It describes how much acid is in something, so measuring acidity tells you how 'sour' or acidic a substance is.
