Awesome, thanks for the corrections!

I went over all the corrections you gave me and I have a couple of questions regarding them.
2. With is + something + preposition, the word order changes, and you use a + lenition instead of a'/ag with the verbal noun:
so ‘cluich’ also adds an ‘-e’ at the end when it is lenited? This is something I have to just memorize by heart right? (i thought lenition meant adding an ‘-h-‘ before the first consonant)
3. use the plural of mionaid
Dh'ith mi briosgaid o chionn cóig mionaidean.
I just have to memorize the plural forms by heart right? There are no rules that govern what specific endings nouns receive right?
Tha mi air briosgaid ithe.
a. this means “i have just eaten” but what grammar pattern is this? (this looks like the alternative passive voice construction but I’m not sure since it has an active voice meaning/tr*nsl*t**n…)
b. what roles does ‘air’ play here? (from my little knowledge of Irish it looks like the reflexive particle but that is totally a guess only…)
6. When you have a string of nouns, the last one is in the genitive,
aig toiseach a' bhliadhna
In my notes I have the following listed regarding the genitive case of nouns:
For the second noun, the one which is in the genitive case:
the masculine article is: a’ + lenition/an/an t the
feminine article is: na
for the masculine noun, how do you know which nouns receive (a’ + lenition OR an OR an t) ??
Bha e tinn aig toiseach a' bhliadhna, ach tha e gu math a-nis
‘gu math’ means ‘good’, right?
7. Chaidh a chas a bhris(t)eadh
I’m confused with ‘bhris(t)eadh’ because it seems like this word is both of what you list in #2 as two separate things. (a + lenition AND (ag/a’) + the verbal noun) ‘a + lenition’ would be ‘a bhris’ and (ag/a’) + lenition would be ‘a’ briseadh’ I’m lost… Also, I don’t what the ‘t’ in parenthesis means…??
past of chan urrainn do is cha b' urrainnn do
a. ‘chan’ and ‘cha’ are the same right? ‘cha urrainn do’ & ‘chan urrainn do’ are the same thing, correct?
b. is (cha b’ urrainn do) the past habitual tense instead of the past tense?
agus air an adhbhar sin cha b' urrainn dha tighinn dhan sgoil
a. ‘tighinn’ is the infinitive of the verb meaning ‘to come’ So, an infinitive is used here in this sentence instead of ‘a + lenition’ or ag/a’ + verbal noun, correct? Is this some kind of grammar rule or does this “just happen” in this particular case?
b. ‘dhan’ means ‘do’ + ‘an’ ? this is another thing I just have to memorize, right?
10. Bha mi a' gabhail bidhe an-siud mus do ghabh mi fios gun robh cearnan anns a' chidsin agus dh'fhalbh mi anns a' bhad.
a. genitive forms of nouns have to be memorized as well, correct? I ask this because I wonder how you got ‘bidhe’ from ‘biadh’…
b. ‘an-siud’ means ‘there’, right?
c. in the past tense of ‘gabh’, ‘do’ is optional, correct?
d. ‘gun robh’ is the affirmative relative past pronoun meaning ‘that’, right?
e. so how do you express ‘there is/are’ in Scottish Gaelic? ‘gun robh cearnan anns a' chidsin’ just means ‘that roach in kitchen’ …? where is the verb here?
I'd use a different tense here: I had been after doing X = Bha mi air X a dhèanamh
a. I don’t see ‘dhèanamh’ in the dictionary…
b. also ‘bha mi + object + ag/a’ + verbal noun’ is the past progressive tense, correct?
11. Bha mi air laighe ann an-siud trì uairean (a thìde) mus do chaidil mi.
‘a thìde’ - what does this mean here? (I know that ‘thìde’ means ‘time’ but…)
The preposition you need is mus + dependent form of the verb
so the dependent form of the verb = ( ‘do’ + the lenited form of the verb + personal pronoun’ )
Bidh thu air ithe deich mionaidean (a thìde) nuair a chrìochnaicheas/sguireas mi.
I think ‘chrìochnaicheas’ comes from ‘crìochnaich’, right? Is ‘chrìochnaicheas’’ the verbal noun of ‘crìochnaich’? ( ‘chrìochnaicheas’ looks like ‘crìochnaich’ plus lenition and ‘-eas’… and ‘sguireas’ looks like ‘sguir’ + ‘-eas’… ) Why is there an ‘a’ before ‘chrìochnaicheas’ ?
Tha e ag iarraidh gun tèid mi dhachaigh a-nis
‘gun’ is a relative pronoun ‘that’ here, right?
18. Chaidh mo bhaisteadh trì tursan ro dhà mhìle 'sa h-aon.
I don’t see ‘tursan’ in the dictionary.
20. Dh'fhuirichinn nam pàidheadh e rium tuilleadh/a bharrachd.
how did you get ‘pàidheadh’ from ‘pàigh’ (it looks like you removed ‘-gh’ and added ‘-dheadh’ but what grammar pattern is that…? )
Dh'fhuirichinn nan toireadh e tuilleadh airgid dhomh.
how did you get ‘toireadh’ from ‘thoir’ (looks like you removed the lenition and added ‘-eadh’ ?? why)
21. Bhiomaid air an taigh a thogail nam biodh airgead gu leòr air a bhith againn
a. ‘Bhiomaid air an taigh a thogail’ -> what grammar pattern is this? (it looks like [conditional of ‘to be’ + ‘air’ + object + lenited verbal noun] ?? )
b. ‘taigh’ means ‘house’ right?
c. I thought ‘biodh’ should be ‘bhiodh’ here… (i thought ‘biodh’ is used in questions and ‘bhiodh’ is used in affirmative/negative statements…?)
d. why is ‘air’ here?
e. what role does ‘a bhith’ play here? ( i know it means ‘to be’ but why is it here?)
Thank you!
