preventing a lapse

Etymology
Etymology Information

'antilapse' originates from combining the prefix 'anti-' and the noun 'lapse'. 'anti-' ultimately comes from Greek 'anti' where it meant 'against', and 'lapse' comes from Latin 'lapsus' where it meant 'a slipping, fall'.

Historical Evolution

'antilapse' developed in modern legal English from the hyphenated phrase 'anti-lapse' (used to mark a rule countering lapse of gifts). 'Lapse' itself derives from Latin 'lapsus' (from the verb 'labi' 'to slip'), passed into English via Old French and Middle English before combining with the Greek-derived prefix 'anti-'.

Meaning Changes

Initially the elements meant 'against' + 'a slipping/fall'; over time the compound came to have the specialized legal meaning 'preventing the lapse (failure) of a testamentary gift'.
