Morphology

fatal = fat + al

Although it shares historical material with fate, the modern sense 'causing disaster or serious consequences' is a semantic extension that learners cannot reliably derive from the component parts.

Etymology

Fatal comes from the Latin fatum, which means 'fate' and is the idea of a result you cannot change. That sense of a final decision is why fatal can mean 'causing disaster' or a mistake that decides everything.
