Just beginning Irish, but I've already seen stuff like: Maidin mhaith (good morning), An fear agus an bhean (the man and the woman), etc. And I've looked up how to pronounce each aspirated consonant broad and slender, but when do I use them instead of a regular consonant? Does it have anything to do with feminine words (notice in my example above, "fear" is not aspirated, but "bhean" is)?
