"Spittly" is a word that is not recognized in either the Oxford or the Merriam-Webster dictionaries. However, one possible way to spell it based on its pronunciation is /ˈspɪtli/. This would suggest that the first syllable is pronounced as "spit" with a short "i" vowel sound and the second syllable is pronounced with a short "i" sound followed by a silent "e". Nonetheless, without a context, it is unclear what the meaning of the word may be.
