The word "Hannahs" is a plural form of the name "Hannah". The correct spelling is determined by the English language's rules of pluralization by adding an "-s" at the end of the word. The pronunciation of "Hannahs" is /ˈhænəz/ (HAN-uhz). The first syllable "Han" sounds similar to "man" and the second syllable "nahs" sounds like "nuzz". It's important to note that capitalizing the name and adding an apostrophe beforehand, like "Hannah's", represents possession, not pluralization.
