Wenden is a Middle English verb derived from Old English wendan that eventually became the modern English wend, which is mostly seen and heard in the construction "to wend one's way." That phrase goes back to the 13th century and had the same meaning as it does today: "to proceed on one's way." In the past, wend was also generally used with the meaning "to go," and people would wend to all kinds of places.

In modern English, when we encounter wend, it is almost always in the sense "to proceed on" and in the form "to wend one's way." In that regard, wend is a fossil word.

However, you may occasionally spy wend without way—without any object, for that matter. This use of the word is relatively infrequent, but it does exist, which means that wend can only be considered a fossil in its transitive use—that is, when it has way as its object.

You may be wondering if the past tense verb went is connected with wend. In fact, went was originally the past tense and past participle of wend. In the 13th century, went was then adopted as a variant past tense for the verb go in some of its senses. By the end of the 1500s, went had replaced the other past tense forms of go and wend developed one of its own—wended.
