Morphology

post + meridiem

The phrase is a literal Latin compound: post = 'after' and meridiem = 'midday', so the meaning 'after midday' (i.e., p.m.) is directly derivable from the parts. In practice these are Latin roots that many B1 learners may not know, but given knowledge of the constituents the composition is transparent and predictable.

Etymology

Post meridiem comes from Latin words post meaning 'after' and meridiem meaning 'midday' or 'noon'. Think of the clock hand moving past 12 — that image explains why post meridiem is used for times 'after 12:00 in the day' and why we shorten it to p.m..
