Here are some examples of how it's used in a sentence:
* Mae taith hir i'r lle hwnnw. (It's a long journey to that place.)
* Roedd ein taith i'r mynydd yn ddiddorol iawn. (Our journey to the mountain was very interesting.)
* Hoffwn fynd ar daith i'r Eidal. (I would like to go on a trip to Italy.)
Note: You could also use siwrnai which means "voyage" or "expedition", but it's not as commonly used as taith.
