Learn Spanish (Latin America): Tengo una correa tuya; la veo en la mesa. - I have a leash of yours; I see it on the table.

Tu correa means "your leash" and refers to a specific one. By using the indefinite article una with the long possessive tuya after the noun, it translates to "a leash of yours." You use this structure when you want to refer to one of their leashes in general, rather than the only one they own or a specific one you were already discussing.

Why does the possessive word end in an "-a" (tuya)?

Even though it comes after the noun and translates to "of yours," tuya is still an adjective describing the leash. It must match the gender and number of the feminine singular noun correa. If you were talking about a male dog (un perro), you would use the masculine form: un perro tuyo.

Could I say una tu correa to mean "a leash of yours"?

No, Spanish grammar doesn't allow you to put a short possessive like tu right after an article like una. Whenever you use an article (like un, una, el, or la) before a noun, any possessive you add must be the long form (tuyo, tuya, etc.) and must be placed immediately after the noun.

Why does the second part use la veo instead of lo veo for "I see it"?
