The in/on/at system for both time (at 5, on Monday, in May) and place (at home, on the table, in Prague)
I can place events and objects with in/on/at using the point–surface–container logic.
Look at these examples. Can you spot the grammar pattern?
The meeting is on Tuesday at 9:30 in room 12.
The meeting is on Tuesday at 9:30 in room 12.
I'll wait at the bus stop on Charles Street — we can read in the café later.
I'll wait at the bus stop on Charles Street — we can read in the café later.
Pay attention to the highlighted parts. What do they have in common?
One zoom-lens logic covers time and place:
| at (point) | on (line/surface) | in (container) | |
|---|---|---|---|
| time | at 5 o'clock, at night, at Christmas | on Monday, on 4 July | in May, in 2026, in the morning |
| place | at home, at the bus stop, at work | on the table, on the wall, on the bus | in Prague, in the kitchen, in the box |
Memorize the odd ones: at night but in the morning; on the bus/train but in the car.
