The word "kiner" is a unique spelling for the word "keener". The pronunciation is /ˈkiːnər/, with the stress on the first syllable. The "k" sound at the beginning is a variation of the traditional "c" sound, but is still pronounced the same way. The "e" before the double "e" in "keener" is what creates the "ee" sound. While "kiner" may not be the most common spelling, it is still a valid variation of the word.
