When do I use "mi" vs. "mío"? Also: "Tu" vs. "tuyo"?
When is correct to use "tuyo" and when is it correct to use "tu"? Also, "mi" and "mío"?
That last response may have been a little unclear (at least, it was to me)
mi, mío, mía, tu, tuyo, tuya can be long and short form possessive adjectives and may have nothing to do with possessive pronouns (el mío, la mía, el tuyo, la tuya, etc.)
Apparently it needs to be answered one million and one times.
The short form possessive adjective is used before the noun and the long form possessive adjective is used after the noun.
