Are there any welsh words starting with th?

You're right to be curious! There are no Welsh words that start with "th" in the standard, modern Welsh language.

Here's why:

* Sound System: Welsh has a different sound system than English. The "th" sound doesn't exist in Welsh.

* Phonetics: The "th" sound is represented by the letters "dd" or "th" in Welsh, depending on the pronunciation.

* Borrowed Words: While there are some borrowed words from English, these are generally avoided in formal Welsh usage.

Examples:

* "The" in English becomes "Y" in Welsh.

* "Thank you" in English becomes "Diolch" in Welsh.
