Morphology

ceteris + paribus

This is a Latin fixed phrase whose constituents are not English words and have no clear dictionary definitions for an English learner, so a B1 learner who 'knows the constituent words' would still not be able to derive the meaning. Although the phrase is widely borrowed in academic registers across languages, it is lexicalized as a set formula meaning 'all other things being equal' and functions idiomatically, making it opaque to average B1 learners.

Etymology

Ceteris paribus is a Latin phrase that literally names ceteris 'other things' and paribus 'equal'. It was used to mean 'if nothing else changes', so today it means 'when all other relevant factors stay the same'.
