動詞
speed (third-person singular simple present speeds, present participle speeding, simple past and past participle sped or (主に英国用法) speeded)
- (intransitive, archaic) To succeed; to prosper, be lucky.
- 1485, Sir Thomas Malory, chapter 1, in Le Morte Darthur, book I:
- 18thc., Oliver Goldsmith, Introductory to Switzerland
- (transitive, archaic) To help someone, to give them fortune; to aid or favour.
- God speed, until we meet again.

使用する際の注意点
- The Cambridge Guide to English Usage indicates that sped is for objects in motion (the race car sped) while speeded is used for activities or processes, but notes that the British English convention does not hold in American English.
- Garner's Modern American Usage (2009) indicates that speeded is incorrect, except in the phrasal verb, speed up. Most American usage of speeded conforms to this.
- Sped is about six times more common in American English (COCA) than speeded. Sped is twice as common in UK English (BNC).
