Prepositions — Quick Revision

Time Prepositions (Funnel Rule)

• in = big (months, years, seasons, centuries) — in March, in 2026
• on = medium (days, dates) — on Monday, on 21 March
• at = small (exact time, festivals) — at 5 PM, at Eid
• Exception: "at night" (not in the night)

Since vs For

Since (point)	For (period)
since 2010	for 10 years
since Monday	for 3 days
since morning	for 5 hours

The "TO not THAN" Group

senior to | junior to | prefer to | prior to | superior to | inferior to

NEVER use "than" with these words!
