English trivia (sorry, jordy): "a" is to "an" as "thy" is to "thine". That is, "thy" comes before a consonant, and "thine" comes before a vowel. "Thy seeds", "thine acorns".
@noelle It’s funny because I was just wondering what the difference was
@noelle Do you know if this is related to the phrase “mine own”
@fluffy @jordyd Ah, that's the example I was looking for earlier! I used "orange" instead (originally "a narange", as seen in Spanish "naranja" etc.).
