Ношу или нашу

Both "ношу" and "нашу" are correct words in Russian, but they have different meanings depending on the context. "Ношу" is a form of the verb "носить," which means "to wear." For example, you can say "Я ношу новую рубашку" (I am wearing a new shirt). "Нашу" is a form of the possessive pronoun "наш," which means "our." For instance, you can use it in a sentence like "Это наша книга" (This is our book). So, choosing between "ношу" and "нашу" depends on whether you intend to express wearing something or showing possession.
