wherewith

The word wherewith is an old word with two main uses. Most often, it means "with which," "by which," or "by means of which." In that use, it points to the thing used to do something. For example, an older text might ask, "Wherewith shall we light the fire?" meaning "With what shall we light the fire?"

It also has a noun sense meaning the means or resources needed for a purpose. In that sense, someone might say a family lacked the wherewith to travel, meaning they did not have the money, tools, or practical support to do it. This noun use is less common today, but it is real and worth knowing.

Because the word is now rare in normal speech, it usually feels literary, formal, biblical, or historical. You are more likely to meet it in older writing than in modern conversation. The related word wherewithal is far more common today and carries the idea of having what is needed to get something done.

Classic English has many examples of wherewith. In the King James Bible, for example, the line "wherewith shall it be salted?" uses the word to mean "with what" or "by what means." That is the heart of the word: it asks what thing, method, or resource makes an action possible.

So if you come across wherewith, think of a doorway into older English. Sometimes it is simply asking "with what?"; sometimes it is talking about the means available. In either case, it carries a strong old-world tone that can sound elegant, dramatic, or deliberately antique.
