Morphology

a + posteriori

This is a Latin loanphrase whose parts are not transparent English constituents: 'a' is an English article but 'posteriori' is not a common English word a B1 learner would know, so the meaning ('based on experience') cannot be derived from the parts. Although the phrase appears in many languages and in academic contexts, its technical epistemological sense is not predictable for an average B1 learner who only 'knows the words'.

Etymology

A posteriori literally means 'from what comes after' and gives the simple image of learning after you have seen what happened. So, a posteriori is used to say an idea or judgement is based 'on experience' or 'after observing facts'.
