Morphology
quadratic = quadrate (semi-transparent) = quadr + ic
The adjective is formed with the combining form 'quadr-' (relating to square/four) plus '-ic', but the link between 'quadr' (four) and 'second power/square' is not fully obvious to many learners.
Etymology
Quadratic comes from the Latin root quadr- and quadratus 'square'. A helpful way to remember it is to think of squaring a number (multiplying a number by itself), so quadratic describes something that involves the second power.
