anti-siphon
|an-ti-si-phon|
/ˌæn.tiˈsaɪ.fən/
prevents siphoning
Etymology
'anti-siphon' is a modern compound formed from 'anti-' and 'siphon'; 'anti-' originates from Greek 'anti-' meaning 'against', and 'siphon' originates from Greek 'siphōn' meaning 'tube' or 'pipe'.
'siphon' came into English via Latin and Old French from Greek 'siphōn'; the compound 'anti-siphon' developed in modern technical English to name devices and features that act against the siphoning effect.
Originally, 'siphon' referred to a tubular device for drawing off liquid; over time the compound 'anti-siphon' evolved to mean a device or characteristic that prevents that drawing-off (i.e., prevents siphoning or backflow).
