二、occasion的用法

1、occasion

2、occasion: [14] Like English befall, occasion depends on a metaphorical connection between ‘falling’ and ‘happening’. Its ultimate source is the Latin verb occidere ‘go down’, a compound formed from the prefix ob- ‘down’ and cadere ‘fall’ (source of English cadence, case ‘circumstance’, decadent, etc). The figurative notion of a ‘falling together of favourable circumstances’ led to the coining of a derived noun occasiō, meaning ‘appropriate time, opportunity’, and hence ‘reason’ and ‘cause’.English acquired it via Old French occasion. Also from Latin occidere comes English occident [14], a reference to the ‘west’ as the quarter in which the sun ‘goes down’ or sets.=> cadaver, cadence, case, decadent, occident

The notion is of a "falling together," or juncture, of circumstances.
