The words imply and infer are worth adding to your repertoire as their formal and academic tone and meaning lend academic style to your writing. Unfortunately, they are quite close in meaning and thus easily confused.

example: The article implied that the government minister knew about the improper use of the funds.
1.1 (of a fact or occurrence) suggest (something) as a logical consequence.
