Common Preposition Mistakes English Learners Make
Prepositions are one of the most challenging parts of English grammar. Even advanced English learners sometimes use the wrong preposition. This guide covers the most common preposition mistakes and how to fix them.
In, On, At — Time and Place
These three prepositions cause the most confusion. For time: use "at" for specific times (at 3 PM), "on" for days (on Monday), and "in" for months and years (in June, in 2026). For place: use "at" for specific locations, "on" for surfaces, and "in" for enclosed spaces.
Common Mistakes with "For" and "Since"
Use "for" with a duration (for three years, for two hours). Use "since" with a starting point (since 2023, since Monday). English learners often say "since three years" which is incorrect — it should be "for three years."
Mistakes with "To" and "For"
Use "to" for destinations and indirect objects: "I go to school," "Give it to me." Use "for" for purposes and benefits: "This is for you," "I study for my exam."
Prepositions After Verbs
Some verbs require specific prepositions: "depend on," "believe in," "apologize for," "arrive at" (a place), "arrive in" (a city or country). Keep a list of these verb-preposition combinations and practice them regularly.
