Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Treating lonely at as a fixed phrase

At usually marks the location where the feeling occurs, not a special adjective-preposition combination.

✓ She felt lonely at work.

Using lonely of

Lonely is not normally followed by of in standard English.

✕ He felt lonely of his friends. ✓ He felt lonely without his friends.

Using in for exact points or events

At is more natural for schools, events, and workplaces as locations.

✕ She felt lonely in school. ✓ She felt lonely at school.

1. Many people feel lonely ___ a new city.
