Not if it's brandable you are looking for. It just needs to be pronounceable, so you just need to come up with a few syllables and string them together. e.g.

1. Optionally add a consonant, e.g. t
2. Optionally add another consonant that changes the previous sound, e.g. h (To make th), not b (To make tb)
3. Add a vowel or the pseudo vowel y, e.g. u (To make thu)
4. Optionally add an r or another vowel, e.g. r (To make thur)
5. Optionally add a cosonant, e.g. f (To make thurf)
6. Repeat the process to add more syllables to the word.
