The word "fatherships" may seem unusual, but it follows a common pattern in English. The suffix "-ship" can be added to many nouns to create a new noun indicating the state or quality of being that noun. In this case, "father" becomes "father-ship," meaning the state or quality of being a father. When "s" is added to the end, it becomes "fatherships" /ˈfɑðərʃɪps/. This can be heard as "fah-thur-ships" with a stressed syllable on the first and third syllables.
