woke

"to become awake," a Middle English merger of Old English wacan "to become awake, arise, be born, originate," and Old English wacian "to be or remain awake," both from Proto-Germanic *wakjanan (source also of Old Saxon wakon, Old Norse vaka, Danish vaage, Old Frisian waka, Dutch waken, Old High German wahhen, German wachen "to be awake," Gothic wakan "to watch"), from PIE root *weg- "to be strong, be lively."

Causative sense "to rouse from sleep" is attested from c. 1300. It has past tense woke, rarely waked (and that usually in the transitive sense) and past participle waked, rarely woke or woken. Related: Waking.

These usage guides for awake, awaken, wake, waken are distilled from those in Fowler and Century Dictionary:

1. Wake is the ordinary working verb; it alone has the sense "be or remain awake" (chiefly in waking).

2. Awake and awaken are chiefly used in figurative or transferred applications (A rude awakening).

3. Waken and awaken tend to be restricted to the transitive sense, awake being preferred in the senses related to arousing from actual sleep.

4. In the passive, awaken and waken are preferred, perhaps owing to uncertainty about the past participle of forms of awake and wake. (The colloquial 2010s use of woke in relation to political and social awareness is an exception.)

5. Up is commonly used with wake, but rarely with the others.
