antiphasic
|an-ti-pha-sic|
/ˌæn.tɪˈfeɪ.zɪk/
opposite phase
Etymology
'antiphasic' originates from Modern English, formed from the prefix 'anti-' and the adjective 'phasic' (from 'phase'), where 'anti-' meant 'against' or 'opposite' and 'phase' ultimately comes from Greek 'phasis' meaning 'appearance/manifestation'.
'antiphasic' developed by attaching the adjectival suffix '-ic' to the noun 'antiphase' (itself from 'anti-' + 'phase'); 'phase' entered English via Latin/French from Greek 'phasis'.
Initially it meant 'being in opposition of phase' (opposite phase), and over time it retained this technical meaning in fields like acoustics, electrophysiology, and signal processing.
