Common Mistakes

Do not confuse out meaning 'not allowed' with out meaning 'outside.'
Do not use come out as a synonym for outed when someone else reveals a person's sexuality; that is a different sense.
Knocked out is not the same as the adjective out in every context; it specifically means unconscious or defeated.
Out has many adjective uses, so check the context before choosing a synonym.
