This may be a dumb question but what do letters in brackets mean? I was reading an article about the West Bomberai languages when i came across: I saw something like:
*[a/o]n
*k[a/o]
I saw this everywhere including the proto-language of the language family.
am[i/u]n
k[i/u]m[i/u]
[ja]ŋgal
Also including the 'V' inside words, such as
tVmber
I also saw one in the Proto-Trans-New-Guinea:
*kobutu, *kv(mb,p)utu, *mUtUna; *mVtVna
I get so confused when i see it. Also, what does the C mean? I saw something like:
kat(i/e)C
