The word "grannis" may seem confusing in terms of its spelling, but it can be easily broken down using the International Phonetic Alphabet (IPA). The correct pronunciation is /ˈɡrænɪs/, with the stress on the first syllable. The spelling may deviate from what one might expect because the "i" in "grannis" is a short vowel ("æ") and not the more common long vowel ("ai"). To remember the spelling of this word, think of it as "gran" followed by the short "is" sound.
