Good day to you! I'm a fan of the little lizard peoples, as you will soon be able to tell from this post. I had noticed what I think is a shortcoming of PF2e in regards to them, which I believe has an easy solution as well.
Kobolds, a widespread ancestry with a large population, in my opinion, cannot have their culture represented as much as I think could be possible.
For those not in the know, unlike most ancestries, Kobolds do not possess a unique language, instead speaking Sakvroth (previously named Undercommon).
This is a major mistake in my opinion, as language is a cornerstone of culture.
Language in all cases carries generations of history, stories, and life experiences of the people who speak it.
Even the most secluded, localised, and smallest-in-population ancestries possess their own language in Pathfinder.
Samsaran speak Samsaran, Vanara speak Vanara, Wayang speak Wayang, Tanuki speak Tanuki, it goes on.
In my view, the biggest strength of Pathfinder as both a setting and a system, is how it can portray as well as represent so many different cultures, both those inspired by real-life ones or those purely fantastical.
This is to say, it bums me out Kobolds seemingly got the short end of the stick.
It is almost as if they possess no agency of their own, which is not true! We all know, and some of us love, how driven these little buggers are!
Allow me to also step back and consider this issue from the perspective of lore. Kobolds being fluent in Sakvroth makes more than perfect sense. Usually living underground, Kobolds are a communal sort, which heavily depend on cooperation between each other and other beings which dwell beneath the ground.
If anything, it would arguably make less sense were they not able to speak it.
That being said, again, it is questionable that Sakvroth serves the role as their "main" language.
It almost suggest Kobolds never progressed as a culture and a people from merely adopting a language commonly spoken underground.
I would like to bring up Gnomes as an example here, as I think they show what how this issue could be resolved perfectly.
Gnomes, a numerous and storied peoples, possess their own language--Gnomish. But it is hardly the only one they speak! Gnomes originating from the first world, they also speak Fey!
I think Sakvroth could fit wonderfully in the same role for Kobolds.
As a final paragraph, I would like to also approximate the number of other ancestries which share the issue of not having their own language.
Using AoN as a source, which lists 49 ancestries, out of all of them there are only 16 ancestries which do not possess their own language, that being:
Awakened Animal, Fleshwarp, Ghoran, Kobold, Poppet, Sarangay, Skeleton, Sprite, Yaoguai, Athamaru, Centaur, Fetchling, Kitsune, Merfolk, Minotaurs, and Leshys
Out of these 16, some however aren't distinct cultures, but are rather either:
A: A transformed member of a different ancestry (ex. Fleshwarps and Skeletons) or
B: Beings created spontaneously, and often as a singular individual, having no time or populous to create their own culture (ex. Leshy, Poppets)
Striking those off the list, we're now left with:
Ghoran, Kobold, Sarangay, Sprite, Athamaru, Centaur, Kitsune, Merfolk, Minotaur
They are quite unfortunate, this group of 9, I mean.
But hey, all of this to say
Come on Paizo!
Goblins speak Goblin.
Let Kobolds speak Kobold too!
