What is the term when, in writing, a word is incorrectly replaced by a similar sounding word?
I think this occurs more commonly with popular phrases where the writer has only heard the word being used in speech, and hasn't seen it in text.
- Things took a turn for the worst - where it should be worse
- These events are unpresidented - where it should be unprecedented
I think this is a different issue than misspelling, because the writer is unaware of the proper use of the word they have written, even if they have spelled it correctly.
The most relevant term I have seen is misword, but according to the Merriam-Webster, it is for a word that is "wrongly spoken" not written.
EDIT: This also includes words that are similar sounding, but not homophones.
EDIT2: Using the wrong word when writing, not in conversation
