How it works
Prepositions often belong to patterns rather than rules that transfer word for word across languages. Learn at/on/in for common time and place relationships, to/from/through for movement, and frequent combinations such as responsible for, available to, comply with, and apply for. A wrong preposition can change meaning or sound unnatural even when the sentence remains understandable. Collect phrases from original content in complete chunks and create a contrasting example for each.

Practice
- Sort twenty time/place examples by at, on, and in.
- Build cards for ten verb/adjective-preposition chunks.
- Record a route description using to, through, past, and toward.
Show the answer key
- Choose prepositions from the relationship, not translation alone.
- Chunk cards should include the whole pattern and an example.
- Movement prepositions should create a coherent spatial route.
