Morphology

PIR = private + information + retrieval (opaque) = P + I + R

PIR is an initialism whose letters do not convey meaning to learners; understanding requires knowing the expansion 'Private Information Retrieval'.

Etymology

The word PIR comes from the phrase Private Information Retrieval, where 'private' means 'hidden' and 'retrieve' means 'to get'. So a PIR is a way to get one item from a database while keeping which item secret.
