"Cuid," as I understand it, is used when you have a portion of something or it isn't all you'll ever have, as well as with mass nouns. Basically, it will be used with things like clothes, money, books, or hair, but not with things like family members or body parts.
If anybody else can correct me if I am wrong or missing something, please do.
This one is connected to 'tirim', to be dry.
You are probably thinking of the similarity with tiomáint (driving), which amusingly is so close to tiomain (swearing).
Best place for all verb forms is http://www.teanglann.ie/ga/fgb/tiomáint or some book listing verbs. Duolingo woukd waste time, and only get snide comments about 'errors' if they were compiling a full list...
The other languages have links you can click on every time you see a new verb with the conjugations. It is so helpful! I can't keep how these verbs are conjugated straight in my head without seeing them conjugated. I mess it up all the time. And I look at your link but don't see the verb conjugated there. I would love to find an Irish verb book. I have seen a few but they are more than I want to pay. :( Right now I just try to write them all down as they come up but I never get them completely conjugated.
The link broke at the á... If you use the search field you will find all the conjugations. As in http://www.teanglann.ie/ga/gram/tiomain/
Use the 'EN' link at top to see the name of tenses and modes in English. As in http://www.teanglann.ie/en/gram/tiomain/
Use the first (green) square icon to see the verb meaning)
Use Google to find the likes of http://www.gaeilge.org/ConjugatingRegularVerbs.pdf
Or Google images for https://www.google.ie/search?q=irish+verbs+made+easy=isch For cheatsheets...
Now that was extremely helpful! Thank you so much. But see I tried to look up the verb "to dry" and it couldn't find it. This is the same problem I have every time. We get a few conjugations of the verb on Duo but I can't look them up because it doesn't actually give me what "to dry" is. I tried looking it up in the English/Irish part but it gave me all sorts of "dry" words and phrases but not that one......I tried clicking on the words on the side and finally found "triomaigh" which I never would have guessed was the verb I was looking for. That is why I would love to have them conjugated here, lol.
Thank you very much. I'll also use this a lot. As well as Becky, I have found very difficult to grasp verb structure within this course. I mean, at this point one learn many verbs just by sheer repetition, but I hope that in the future the conjugations and overall verbs get improved. The same with noun cases.

In a moment of particular carelessness, my fingers translated this sentence literally without my brain interfering and I typed "I dry my share of clothes." While (as far as I know) this is a literal translation, I was surprised to get marked wrong. Is there a particular reason why this translation is incorrect?
As far as cuid with people or body parts, 'Cuid de na daoine', 'cuid againn', 'Cad é mar atá do chuid páistí?', 'Seo mo chuid mac', 'mo chuid gruaige', etc.
