How is one to determine gender? Is there anything one can do to recognize it apart from rote memorization, object by object?
Why is 'An-t" added before ìm math?
Because it’s the butter, it needs the definite article (an) in front of it. And the definite article prefixes t- before mesculine nouns starting in a vowel (an t-ìm the butter, an t-athair the father, an t-ainm the name…).
But why not Tha an t-ìm?
Because: 1. in English it’s the good butter, not the good butter is, 2. that would not even be a correct sentence – either in Gaelic or in English.
