Sense: verb/1
All four words describe something finishing, but they differ in scope and connotation. 'Expire' is the most specific — it is used for things with a legally or officially set end date, such as passports, contracts, or memberships. 'Lapse' implies that something ends because of inaction or neglect (e.g., an insurance policy lapses when you stop paying premiums). 'Run out' is informal and broader: supplies, time, patience, or money can run out. 'End' is the most general word and can replace any of the others, though it lacks the precision of 'expire' for legal validity. For example: 'My visa expires next month' (specific end date), 'I let my gym membership lapse' (neglected to renew), 'We have run out of milk' (supply gone), 'The meeting ended at noon' (neutral finish).

Etymology
From Latin 'exspirare' — 'ex-' meaning 'out' and 'spirare' meaning 'to breathe'. The original sense was simply 'to breathe out'. Over time, the word took on the meaning 'to breathe one's last breath' (i.e., to die), and from there it broadened to describe anything that reaches its natural end, especially things with a fixed duration. The three modern senses (validity ending, dying, and exhaling) all trace back to this core image of releasing breath.
