theen

• ðen, the, thee, theo, theon, theyn, þe, þeen, þene

From Old English þēon (strong class 1), from Proto-Germanic *þinhaną (strong class 3); a cognate of Middle Dutch diën. In later Old English, þēon changed to strong class 2 on the model of tēon, meaning the past participle became þogen; in Middle English, the -g- vocalised to -w-, resulting in a form thowen. Past singular forms in -w- were then analogically created on the basis of this past participle (see the inflection table below).
