WordsWhat you are actually practicing
Time prepositions follow one scale, from the smallest unit to the largest: at for a point in time, on for a day, in for anything longer. At seven o'clock, on Monday, in July.
Learners usually know the words and still choose wrongly, because the choice depends on the size of the time expression rather than on its meaning.
How the game works
You are shown a time expression and four prepositions. Pick the one that belongs before it. A wrong pick reveals the correct one immediately.
Easy uses days and clock times, where the scale is clearest. Medium adds months and seasons. Hard uses the full list, including the fixed expressions that ignore the scale.
The scale worth knowing
at — a point: at 7 o'clock, at noon, at midnight, at night, at Christmas.
on — a day or date: on Monday, on 5 May, on my birthday, on Friday evening.
in — a longer period: in July, in 2024, in winter, in the morning, in the 1990s.
Strategies that actually raise your score
Classify the expression by size before choosing. Is it a point, a day, or a period? One question, one answer — no memorisation needed.
Remember that "morning/afternoon/evening" take in, but "night" takes at. This single exception is worth more marks than any other.
A day plus a part of day uses on. On Friday evening, not in Friday evening — the day wins because it is more specific.
Watch the fixed expressions. At Christmas, at night, in the end — these do not follow the scale and have to be learned as whole phrases.
