What are the different ways to spell wade?

There's only one standard spelling for "wade," and that's wade.

However, there are some uncommon or dialectal variations, like:

* waden: This is a rare archaic form of the verb "wade."

* waid: This is a verb used in some dialects of English, particularly in the northern parts of England and Scotland, meaning "to go" or "to travel." It's not related to the verb "wade."

So, while there are other spellings that exist, they're not considered standard English.
