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”

@jordyd probably!

@jordyd I looked it up, and yes, historically "my" was before consonants and "mine" was before vowels.

@noelle @jordyd and then we have words like “uncle” which were originally “nuncle” but the N migrated across the space!
