IPA: /ʌnˈhæʧt/
KK: /ʌnˈhæʧt/
Describing something that has not yet broken open from its shell, typically referring to eggs.
The unhatched eggs were carefully monitored for signs of life.
Unhatched → It is formed from "un-" (meaning not) and "hatched" (from Old English "hæccan", meaning to cause to break open or emerge from an egg). The word "unhatched" means not having broken open or emerged from an egg.
Think of 'not' ('un-') having 'broken open' ('hatched') — that's why unhatched refers to eggs that have not yet opened.
