The link just goes the the general page. I dug up the exception under "Caibidil a Dó: the adjective (an Aidiacht) / The declension of adjectives (Díochlaonadh na nAidiachtaí)":
the "dentals"-rule is not used with attributive adjectives (so d,t,s are indeed lenited also after nouns ending in d,n,t,l,s) e.g.: an bhean dheas = the nice woman
Thanks! There's a version that doesn't update links; I'll fix it when I can.
I don't understand why you say it doesn't make any difference. In short, has Duolingo made a mistake here or not?
Yes. The issue is teachers who don't understand the language will tell you that DNTLS applies, when that is not true. Native speakers use it, and that's what's important. However, even though native speakers use it, it seems to be slowing declining, probably because of said teachers.
edit Usually words beginning in d, t, or s don't lenite after words ending in d, n, t, l, or s. Since dorcha is attributive, though, the dentals dots rule is ignored. So yeah, what's going on here?
My Irish grammar book notes the equivalent of the “DeNTaLS DoTS” rule only in discussing indefinite genitive nouns when governed by plural nouns which end with a slender consonant, e.g. buidéil bhainne (“bottles of milk”) but buidéil draíochta (“magic bottles”, literally “bottles of magic”). Since feoil isn’t plural, I’d thought that that rule wouldn’t apply. Is the rule applied more generally than in that particular case?
What the hell is "dark meat"? I guessed this as "red meat" but it's apparently not that.
It's referring to the distiction in chicken and other poultry between white and dark meat, I believe.
Now I can, or at least should be able to, express my poultry eating preferences in Irish...
Come Thanksgiving dinner or Christmas dinner:
"Do you want dark meat or white meat?"
"Dark meat, which avian myologists refer to as "red muscle", is used for sustained activity—chiefly walking, in the case of a chicken. The dark colour comes from the protein myoglobin, which plays a key role in oxygen uptake and storage within cells. White muscle, in contrast, is suitable only for short bursts of activity such as, for chickens, flying. Thus, the chicken's leg and thigh meat are dark, while its breast meat (which makes up the primary flight muscles) is white. Other birds with breast muscle more suitable for sustained flight, such as ducks and geese, have red muscle (and therefore dark meat) throughout." [Italics added]
The Irish would also include the definite article - "Is maith liom an fheoil dhorcha".
In English, "vegan" is an adjective in "I'm vegan", but it's a noun in "I'm a vegan". That makes a big difference in Irish, as you use the copular form Is veigeán mé to say "I'm a vegan", but you would only use the adjective to describe a thing that is suitable for a vegan to eat/use, like bróga veigeánach - you would not say tá mé veigeánach.
