I've been having a real hard time trying to gather information about word formation in English, more specifically about the rules involving suffixes that turn verbs and adjectives into nouns. But not only that, because I also need the rules about the changes in spelling and the stress shift in the pronunciation regarding these noun suffixes.
So far I've got a list of "all" suffixes that turn verbs and adjectives into nous and their meanings. However, I haven't found much information about the other topics: spelling changes and stress shift.
Could you help with that, please?
ADJECTIVE - sociable / NOUN SUFFIX: -ity / NOUN SUFFIX MEANING: condition, sate or degree to / SPELLING CHANGE: sociable - sociability / STRESS SHIF: sociable - sociability
