"i"seems to be used for either pronoun
What do you mean? Can you give any examples?
i is the feminine pronoun, she. e is the masculine pronoun, he. There is no neuter pronoun for it in Scottish Gaelic and all inanimate nouns have either a feminine or masculine gender and the matching pronoun is used (eg. i for weather since words for weather, aimsir and sìde are feminine or because that was used at night time and spread from there, as oidhche night is also feminine; but e is used to refer to a day since latha or là, the word for day, is masculine).
