Just include all phonological rules in the phonology section.
Alright, will do.
Yes. CC means ANY two consonants, as long as it's an allowable consonant cluster in your phonology. So if you have both *skal and *tral as possible words, that rule would insert /o/ before both of those.
Okay, just wanted to make sure before I went ahead.
I'm not sure I totally understand your question but let me try to answer. *ren oskal is more natural/likely than *reno skal. To be honest, I'm not so sure *reno skal is allowable but I can't think of a reason it wouldn't be.
Hmm, what I mean is: I'm applying epethetic/prothetic to my conlang -- skal -- so "sk/CC" could be possible with my syllable structure. But does the *reno skal option conflict with that? Because if its alone -- skal -- by using "Ø→o/C___#sC" it would be incompatible with my syllable structure again [which is (C)V(C)], right?
*I'm sorry I was confusing.*
I'd recommend reading up on phonological topics on wikpedia. The pages are usually quite easy to understand and give lots of examples in natural languages. Also, for rule writing it would be good to read up on feature theory...it's more complicated but helps with writing vowel harmony rules, voicing rules and other rules which can't easily be written with just IPA symbols.
I have read and understood some Wikipedia articles, but a lot of the time I can't follow what they are saying. I do try reading the articles a couple hundred times before I ask people on forums though. I'll read up on the articles some more next time before thinking about asking people/on forums.
