antiresonance
|an-ti-res-o-nance|
/ˌæntiˈrɛzənəns/
suppression of resonance
Etymology
'antiresonance' originates from the prefix 'anti-' (from Greek 'antí') meaning 'against' and the noun 'resonance' (from Latin 'resonantia', from 'resonare') meaning 'to resound'.
'resonance' entered English via Latin 'resonantia' (and Old French influence) and became established in scientific usage; the compound 'antiresonance' was formed in modern English (19th–20th century) by combining 'anti-' + 'resonance' to name the phenomenon of suppressed response.
Initially the components literally meant 'against' + 'resound', but in technical/scientific usage the compound evolved to mean 'a suppression or cancellation of resonant response at certain frequencies'.
