Proper grammar and usage are important to all writing, including papers written in APA Style. Incorrect grammar and careless construction of sentences distract readers, introduce ambiguity, and impede clear communication.
The grammar and usage guidelines in the Publication Manual represent only the most common areas of concern for writers—verbs, pronouns, and sentence construction.
If you have questions regarding grammar and usage that are not covered on the APA Style website or in the Publication Manual, consult a trusted grammar reference work or website. If you are student, also consider visiting your university writing center to receive individualized help with your work.
Grammar and usage are covered in Chapter 4 of the APA Publication Manual, Seventh Edition
