making inactive

Etymology
Etymology Information

'inactivate' originates from Latin elements: the prefix 'in-' (from Latin 'in-' meaning 'not') combined with 'activate' (from Latin 'activare', meaning 'to make active' or 'set in motion').

Historical Evolution

'activate' comes from Latin 'activare' (from 'activus' meaning 'active', ultimately from 'agere' meaning 'to do or act'). The negative form 'in-' was attached to 'activate' in English to form 'inactivate' (a back-formation/derivation using the Latin negative prefix and the existing verb 'activate').

Meaning Changes

Initially formed by combining a negative prefix with a verb meaning 'to make active', its meaning has been consistently 'to make not active' or 'to render inactive' in modern usage.
