You’re welcome!

Oh let me explain the difference baxmayaydı case.

I saw you had difficulties with “biləydim” and “bilərdim”.

In baxmayaydi case it is easier than “bileydim” and “bilerdim”. Those completely different grammatical moods. I’ll explain them by breaking down the components.

Let’s start with indefinite future tense which is constructed with “-ar/ər”. Bil —-> bilƏR
However, the negation of this tense is constructed with “-maz/məz”. So it would be “bilMƏZ”. Since there is no “r” to turn into “y”, then its negative version as in the case of baxmayaydi would be “baxMAZdı”.

“İdi” particle gives past tense notion to verbs and moods, it can be used separately or added to the verb/word. For example: sil (delete) —- silir (she/he deletes) —- silirDI (she/he was deleting) — silirDIm (I was deleting)

There is a rule in Azerbaijani that if the word ends with a vowel and the suffix starts with a vowel then ‘linking’ suffixes such as “n”, “y”, or “s” must be place in between. For example: oxu (read) —-> oxuYur (oxu + y+ present tense suffix ur)

Bil (to know) + indefinite future tense (ar/ər) —-> bilər + idi —-> bilərdim —-> I would know/ I would have known (equivalent to english Future in the past tense)

On the other hand, we have a grammatical mood called “arzu şəkli” (desire/wish mood) which is formed by adding “-a/ə” to the verb stem. You can distinguish this tense by adding “kaş” (I wish) before the verb, if it makes sense, then it is this mood. For example:

(Kaş) bizə gəlƏ ——> I wish he would visit us
In case of verbs ending with vowels, then we will need to add “y” between the verb stem and the suffix
(Kaş) mahnı oxuya (oxu + y + desire/wish mood suffix) —-> I wish he would sing songs
Its negation is constructed by adding “-ma/mə” negation suffixes, and since negation suffix ends with vowels and desire mood suffix starts with vowels, then automatically we need to add “y” in between.

(Kaş) gəlməyə - I hope he won’t come

Basically:

Biləydim —-> bil (to know) —-> -ə desire/wish mood suffix ——> idim ( biləidim would be grammatically wrong, that’s why you either say bilə idim pronounced as biləydim or simple convert “i” into “y” - though it can also be counted as linking suffix “y”) —-> I wish I knew

So in the end “baxmayaydi
“ (bax + ma negation suffix + linking suffix “y” + wish/desire mood suffix “a” + idim) means “I wish he didn’t look at […]”

As for “baxmağı”, in Azerbaijani infinitives can be nominalized and nouns and/or nominalized verbs/adjectives do have grammatical cases, as well as nominalized verbs/adjectives can be in plural, possessive case etc everything that a noun would do.
So “yar baxmağı” —- baxmağı here is nominalized, it is in 2nd group of noun phrases (I explained this to you if you remember, 1st one has no indication e.g qirmizi kitab [red book], 2nd one having 0 suffix in the first component and having mensubiyyet suffix in the second component e.g bayram gülü see our discussion here).
So “yad baxmağı” has the same grammatical case as “yar gözləri (lover’s eyes)” in Azerbaijani. However yar baxmagi in English means “foreigner looking at”.

Translation of the line:
Yad baxmağı bir yana,
Yar yada baxmayaydı.

I can bear others looking at [my lover]
I wish my lover wouldn’t look at others
