The mistake to watch for

Incorrect Correct
He speaks English fluent. He speaks English fluently.

This is one of the most frequent errors among English learners. Fluent describes a person (she is fluent in Spanish); fluently describes the speaking.

Where the adverb goes. Put it after the object, not between the verb and the object: She speaks Spanish fluently, never She speaks fluently Spanish. That second order is normal in Spanish and French, which is exactly why it survives so long in learners’ English.
