The spelling of the word "gannaway" might be confusing if you are not familiar with its pronunciation. It is pronounced /ɡəˈneɪwi/ with stress on the second syllable. The "g" at the beginning of the word represents the voiced velar consonant /ɡ/. The double "n" indicates a nasalized vowel sound, /ə/. The following "a" is represented by the long vowel sound /eɪ/, created by two vowel sounds being pronounced as one syllable. The "w" in "gannaway" represents the voiced labio-velar approximant /w/, and the final "y" indicates a short /i/ sound.
I apologize, but I couldn't find a specific definition for the term "gannaway" in any reliable dictionary sources. It is possible that "gannaway" may be a proper noun, a slang term, or a niche term not commonly found in standard dictionaries. If you could provide more context or specify any additional information about the term, I would be happy to assist you further.
