(deionize)
remove ions
Etymology
'deionize' originates from Modern English, specifically formed from the prefix 'de-' (from Latin) and the verb 'ionize' (from 'ion' + '-ize'), where the prefix 'de-' meant 'remove' and 'ion' (from Greek 'ion') referred to a charged particle (literally 'going').
'deionize' changed from the earlier formation 'ionize' (from 'ion' + '-ize') by the addition of the productive English prefix 'de-' to produce 'deionize'; 'ion' itself comes from Greek 'ion', from the verb 'ienai' meaning 'to go', and entered English via modern scientific coinage in the 19th century.
Initially, 'ion' referred to a particle associated with motion ('going'); 'ionize' came to mean 'to form ions', and with the prefix 'de-' the meaning 'to remove ions' developed and has remained stable in modern usage.
