Hi Rocas Faol, my answer here should really be in the Irish Gaelic section because I am giving examples from Irish below in reply to your above post.
Aisling is indeed an Irish Gaelic word, {Scots gaelic being part of that language group and stemming from Irish gaelic in origin} it's a feminine ia-stem noun meaning "dream" or vision", but maybe in earlier language was an -io stem noun.
Aisling is pronounced "Ashling" (not "ex-ling")
[*Old Irish Aislinge is pronounced "as-ling-eh" or maybe "ash-ling-eh"; *this is the language period of about 7-9th C AD from which all later forms right up to the most modern standard Irish, evolved] .
Possessives:
To answer your question on the plural possessives, they are:
1st plural
our = ár (pronounced ore) and this nasalizes any word following it.
2nd plural
"your" = bhur (pronounced woor or voor) and earlier also "far", nasalising the following word.
3rd plural
"their" = a (pronounced "ah") and nasalizing the following word.
Nasalisation: this means that the old ending of a word which used to end in a nasal sound is transferred to the beginning of the next word following it. In modern Irish, the nasalizing sound is shown in writing but in Old Irish it is only written before some letters although it is always understood to be there and is always pronounced even if not written. Nasalisation is also known as
eclipsis.
In the case of your list below, the nasalization is just variously demonstrated
ar
our; precedes nouns beginning with con.
by "with con" above it means "a noun beginning with a consonant" and the nasal sound is shown by writing another consonant before it.
eg. words beginning with the consonants c,t,p,g,b,d all get another letter before them after ár, which makes the sound nazal. Consonants like l,r,n, s stay as they are with no letter infront; f gets a "bh" in front of it to create a nasalized "v" sound.
ar n-
our; precedes nouns beginning with vowel.
this means that an n- is written before the word beginning with the vowel (the hyphen is used optionally)
To answer your questions on the rest of list below:
The possessive pronouns are
1st singular = mo (my, mine)
2nd singular = do (yours, singular)
3rd singular = a (his/her's/it's) each take a different mutation afterwards
1st plural = ár, nasalising (ours)
2nd plural = bhur, nasalising (yours, plural)
3rd plural = a, nasalizing (their's)
These can be combined with other grammatical structures such as the ones you cite below
eg.
(1) As a conjugated prepositional pronoun - this means the pronoun is suffixed to a preposition. From your list below this covers:
d'ár (do + ár) = to our
d'ár (di/de + ár) = from our, etc.
leinn (le + nn (inn,unn,on) = with us, by us, in our possession.
le 'r (le + ár) earlier "lar" (l'ár) with our, by our, for : le ar
(2) with a noun and emphasizing particle which refers back to the posessive pronoun:
eg.
ar n-athair-ne ~ the ne (also ni) is a 1st plural emphasizer so when combined with the noun following the pronoun ár, it emphasizes this really is OUR father. eg. "our own father"...that sort of emphasis.
Best wishes

ps. someone else would have to do this for you for Scots gaelic as I have never learned it and don't speak it. It's probably not too far different.
