I guess you're talking about masculine nouns
after the articlesQuote:
Ní shéimhítear aimnfhocal firinscneach sa tuiseal ainmneach nó cuspóireach uatha ach séimhítear é sa ginideach.
One doesn't lenite a masculine noun in the nominative nor in the accusative cases, but one lenites it in the genitive.
which means you'd say "Tá an
fear ansin" (the man is there). "Feicim an
fear" (I see the man). But "hata an
fhir" (the man's hat).
To lenite = to put a séimhiú on a consonant (you add an h after the initial letters b, c, f, g, m, p after the article in the genitive case: hata an
fhir...)
nominative case = when your noun is the subject of your verb (the man is, the man eats...)
accusative case = when your noun is the direct object of your verb (I see the man, I take the man...)
genitive case = when you have "of" or 's in English (the man's hat, the hat of the man).
Quote:
Ní shéimhítear an aidiacht i ndiadh ainmfhocail fhirinscnigh sa tuiseal ainmneach nó cuspóireach uatha, ach séimhítear é sa ginideach Uatha.
One doesn't lenite the adjective after a masculine noun in the nominative case nor in the accusative case, but one lenites it in the genitive singular.
Same thing:
Tá an fear
beag ansin = the small man is there. (Nominative=subject)
Feicim an fear
beag. = I see the small man (accusative=direct object)
Hata an fhir
bhig = the hat of the small man.
If it's not clear enough, feel free to ask more questions.
