Morphology

syllogism = syllog + ism

Formed from a non-productive combining form 'syllog-' plus the suffix '-ism'; neither element is a standalone, familiar English morpheme, so learners cannot reliably derive the meaning from its parts.

Etymology

The word syllogism comes from Greek parts made from syn/syl- 'together' and -logos 'word' or 'reason', the same root in logic. So, a syllogism is a group of statements put together to reach a conclusion.
