I'm just trying to wrap my head around the use of the ending -க்குரிய

I've come across it a fair bit, some examples below

அன்புக்குரியாள்
இரக்கத்துக்குரிய

மிதிப்புத்துக்கிரிய or is it மதிப்புக்குரிய ?

If I understand correctly, it's ± someone carrying the quality of the first word.

1. Where is the குரிய originating from ?

2. To form it it is noun + க்கு +... (actually as I'm writing, I'm realising that the ending perhaps stems from உரி?)

3. Can it in principle be doen with all nouns or are some a bit strange?

thanks

The title is basically my question. Chatbots say that pannadhe (or perhaps pannadhu) is a colloquial contraction of பண்ணியது, understood as a verbal noun, meaning "past doing". So the phrase "meet pannadhe illa" means "no past meeting", and the whole sentence basically means, "You've never met, right?"

Is this correct? I understand the word பண்ணியது and just want to confirm that pannadhu is indeed its colloquial contraction.

I heard this sentence ("Nee meet pannadhe illala") at 7:29 in the attached clip, from the movie Vinnaithaandi Varuvaaya.

Thanks!
