Translation:Her bringing up
I'm having the hardest time with 'Ei ...' How do I tell the difference between /His/ and /Her/? They're both Ei as far as I see. I'm looking for a mutation if it's 'her', but that doesn't always exist.
Ei masculine causes a soft mutation. Ei feminine causes a aspirate mutation. This only works for the letters, T, C, P, D, G, B, Rh, M, Ll (for soft mutations), and T, C, P(for aspirate mutations) but otherwise it's easy to assume from the general context of the conversation.
Ah, interesting, by Ei masculine, say like A's B, which one is the masculine one, A or B?
By Ei masculine I mean when the person who is owning something is masculine, the gender of the object being possessed doesn't matter. I.E Ei gath (his cat). The way of forming "A's B" in welsh is "B A" e.g "Beiro Morgan",
My understanding is that the difference is at the end, you differentiate "his" or "her" by "e/o" or "hi", but when this part is omitted (which seems like they can), you will only be able to tell it's third person singular without context. see https://cls.byu.edu/welsh/101-Possessive_Chart.html
I could be deadly wrong on this as I am also learning Welsh so I hope someone could jump in and confirm it :D
This is kind of true, in terms of if the pronoun is omitted then if the word starts with a letter that can't be mutated e.g a vowel or s etc then you can't tell but if the word starts with a T, C, P, D, G, B, Rh, M or Ll and it mutates softly then you know it's masculine, and if it starts with one of these letters and it has mutated aspirately (for T, C or P) or not mutated at all (for D, G, B, Rh, M, Ll) then you know it's feminine.
