[p]->[k] sound change outside of Arapaho?

[Šọ̈́gala]

So, from Proto-Algonquian to Arapaho, one of the more notable sound changes that occurred was [p] to [k] (or sometimes to tʃ) in all positions.

I had thought about using this in my secret conlang project, because it's a convenient way to come up with more instances of [k] to replace it after palatalization.

Any thoughts on how come this change is cross-linguistically? Has it ever happened outside of Arapaho?

Depending on the phonology, you can just do it straight off if you don't already have lots of plosives and clusters etc. Look at Polynesian. In any case, it's not a strange sound change in the least.

Labials and dorsals (including velars) are sometimes grouped together as peripherals, because what they have in common is being pronounced at the two opposite peripheries of the oral cavity. The term is especially common in describing Australian languages. Coronal is the opposite of peripheral in this case.

K-ish sounds commonly change to labials via velar-labial intermediary stages. An example would be Romanian where latin kw > p so aqua is apă.

p > kʷ has (most likely) happened in some Athabascan languages (as part of a wider consonant shift where Proto-Athabaskan *ts ends up all over the place in the various dialects of one subgroup of the family: [tθ] in Slavey, [p] in Mountain, [p] ~ [kʷ] in Hare, [kʷ] in Bearlake and Dogrib; since most other plosives and affricates between the alveolar and velar POA (including several labialised ones) generally remain in place, this distribution is probably the result of a shift ts > tθ (> pf) > p > kʷ). The sound change itself is certainly possible; making it unconditional through hypercorrection is fairly radical but it seems naturalistic enough that you can get away with it IMO.

Proto-Celtic *k^w became *p in the P-Celtic branch. ( http://en.wikipedia.org/wiki/Celtic_lan ... d_Q-Celtic )

Certainly, [kʷ] can become [p]. But are there examples of [k] developing into [kʷ] without special conditioning factors?

Also Osco-Umbrian ("P-Italic" as opposed to the "Q-Italic" of Latin and Faliscan), Sardinian (from Latin qu), and Greek (before *a *o). I can't think of anything outside of IE, though.

Some Thai dialects have /kʰw/ > /f/ (merger). This still doesn't help with a search for [p] > [k].

[Vuvuzela]

Proto-Oceanic is reconstructed with a "labiovelar" series, typically assumed to be a set of possibly labialised velarised bilabials. In some languages, these are reflected as simple velars. No-one knows exactly where these phonemes originally come from, though.

[ObsequiousNewt]

labialised velarised bilabials

wut

[Hallow XIII]

pˠʷ bˠʷ etc

actually only pʷ bʷ since that indicates labiovelarisation in the first places

[Nortaneous]

p > f > x > k?

[Yaali Annar]

Sundanese has labial > palatal sound change. The explanation is actually here in this forum:

In some (but not all) words, Sundanese reflects Proto-Malayo-Polynesian (PMP) *w and *b as ʧ initially and nʧ medially (i.e., *w, *b → ʧ /#__; *w, *b → nʧ /V__V). For example, PMP *sawa "python" > Sundanese sanʧa; PMP *badas "gravel, stony ground" > S. ʧadas; PMP *laban "oppose, opponent" > S. lanʧan; etc.

I'm not sure if it's related or not but Indonesian <lompat> and <loncat> both means "jump".
