Which area/tribe has the purest pashto?

[Elite Pakhtun]

"Tsatt" means back, but can mean back of anything. Can even mean a persons back.

I've also heard gharha

[Samandri]

We marwats also use word 'makandai' for neck in addition to 'gharra', .We also use word "Maghzai" for neck......back of neck is chatt ........

[khushal]

Maghza is brain and also we use it for bone marrow.

[khushal]

We use Marai to refer to Adam's apple, We call neck "Ghara", and back of neck "Tsatt", throat is referred to as "Stoona"

Thats funny. We use Gharra for Adams apple.
Shapur, you are from Kandahar right?

[Samandri]

For brain and bone marrow its "Maghaz" (مغز) and ماغزه......."Maghzai" ( مغزې ) is used in the meaning of neck by us

[khushal]

what would be the Pashto word for stubborn?

sar tamba
l

[Sher-E-Punjab]

We punjabis also use word magaz for brain and the word godha for knee.

[khushal]

For knee, we use the word "totakay"

[Shapur]

No bro, I am from Kabul. We've been living in the north for a long time, have relatives in Balkh, kunduz, Baghlan etc but moved to Kabul about 60 years ago

For knee, we use the word "totakay"

Never heard of that word before, We call knee "Zangoon"

Kandahar Pashto indeed has drakhta for tree, seeb for apple khirkai for window. Clearly there is Farsi loan words. It would be interesting if someone elaborate on etymology of these words.
To me saeeb drakht common to Punjabi/Urdu/farsi, khiRkai is used in urdu/Hindi.

As for queta-wals using English words is naturally borrowed from Urdu since Urdu speakers often use English words. "Yaar enjoy karein', 'kyaa baat zabardast restaurant par delicious food khai'

But I would agree loya paktia to paktika you hear least borrowed words.

All iranic languages share ample vocabulary: courtesy predominantly to Avestan, Khotanese-Saka and or Sanskrit (sister-language of Avestan).
The word drakhta comes from Avestan or even PIE (Proto-Indo European) actually dreu= wood, in avestan it become ‘daru’, Sanskrit ‘drau’.
Window is ‘panjereh’ in Farsi.
The word “khirkay” has a retroflex, which is common in both Avestan and Sanskrit.
Apple is indigenous to Central Asia, interesting how Pashto/dari/farsi and indo-aryan word for it is ‘seeb’. Uzbak/kazakh word for apple is ‘alma’

Pashto word for apple is "Manra" مڼه not "seb"

[sterge]

Pashto word for apple is "Manra" مڼه not "seb"

My post has veneers to the other post I quoted.
Anyhoe, Ma[R]ra has a retroflex and you can make an argument that Pashto maintained its ‘originality’, given other abetting ‘arguments’, that still doesn't make "seeb" a non-pashto or just a farsi loanword unless you provide source(s), given that both languages belong to the same umbrella linguistic group, though over time farsi lost retroflex(like most west iranic languages); the syntax is different yata yata yata. Still Dari shares tons of vocabulary with Pashto and that point shouldn’t be ignored.
Furthermore, you can even make an argument that “al(MA)” Kazakh (apple) became ‘Ma[R]ra’, in the same manner PIE(drau) became drakhta.

Thanks for digging up the academic etymology. Unscholarly me have heard plenty words anywhere from hindi to farsi spectrum fall under the PIE umbrella. From my family experience of duties in Barg-e-Matal, more Farsi sprinkled into Nuristan, shows how complex it appears superficially the variety of 'loan words', later under etymological scrutiny to be established as words belonging to same group of sister languages, as you have shown, Sanskrit to Avestan.

However moving to the Kazakh 'Alma', I suspect it may be in the Turkic linguistic group.

Anyhow thanks for the clarification, I am at the periphery of my linguistic knowledge.

You’re welcome.
You are point on: Kazakh does belong to Northwestern Turkic linguistic group; I was trying to recount the roots of Apple tree back to the land of its origin, i.e modern-day southern Kazakhstan. My stance: given Pashtuns have steppe ancestry; it is likely that our ancestors brought the plant and the vocabulary with them.

For knee, we use the word "totakay"

Hahahhahahah...... Never heard of that one before, but... the word you have quoted rhymes with another word which my uncle uses a lot. I won't tell you the word nor the meaning but I was alarmed at the fact that I had never heard it before.
