In English, any words that are homophones except for voiced "TH"?

Factual Questions
1

Are there any two word in English that would be pronounced exactly the same except that one has a voiced “TH” where the other has an unvoiced “TH”?

2

Either vs ether (in some pronunciations)

3

teeth/teethe

thee/the (sometimes)

thistle/this’ll :wink:

4

This is a general rule with english nouns ending with the voiced ‘th’ when they are transformed into verbs. So we see the same thing with oath (n) and oath (v) for example. In many cases the final noun is also lengthened, is in “bath” and “bathed” or “cloth” and “clothed”.

So if the OP wants to make a list of all English nouns ending in the voiced “th”, they should have a similarly long list of homophones of the type they are looking for.

5

sooth (as in “forsooth”) and soothe

6

Archaic but still in use in some contexts: thy / thigh

7

There are a lot of them that fit this paradigm:

breath / breathe
loath / loathe

A little uncommon as a verb, but still existent: wreath / wreathe (to weave into a wreath/wreaths)

8

The last one was actually the only one I could come up with myself, but it didn’t quite cut it.

Teeth/teethe is good in that they’re both common, currently-used words.

I’m wondering, though, if there is an example where the words are current and also unrelated in meaning.
