Morphology

1st-class + mail

The meaning 'a priority category of mail' is directly compositional from '1st-class' (first-class, indicating highest priority or quality) + 'mail' (postal items). This follows a common English modifier + noun pattern and has clear equivalents in many languages, so a B1 learner who knows the constituents will readily infer the meaning.

Etymology

The term 1st-class mail comes from old post offices that sorted letters into 'classes'. The word 1st-class meant the top level, so 1st-class mail was handled first and sent faster, which is why it now means mail with 'priority' delivery.
