APA in text citation: the two forms it takes

By Alberto Gulotta · Updated 4 September 2026 · 8 min read

Every apa in text citation is one of two shapes. The American Psychological Association states it in a single line: “In-text citations have two formats: parenthetical and narrative.” Almost everything else in this subject follows from knowing which one you are writing.

The choice is not decorative. A parenthetical citation keeps the author out of your sentence, so the sentence stays about the finding. A narrative citation puts the author into the sentence, so the sentence becomes partly about who said it. Writers use the second when the source itself matters — a disagreement between two studies, say — and the first the rest of the time.

Then there is the part that generators cannot help with at all, because it happens inside your prose rather than in the list at the end.

A reassuring fact for anyone worried about editions: on the parenthetical-versus-narrative distinction, APA says plainly that “this guidance is the same as in the 6th edition”. The wider author–date system did change — APA marks that page “this guidance has been revised from the 6th edition” — and the best-known change is the one in the table above, where three or more authors now shorten to “et al.” from the very first citation.

One rule lives entirely inside your sentences: what to do the second time you cite the same work. Here the two forms part company, though everywhere else they run in parallel.

There is an exception to the narrative half of that, and it is the one worth remembering, because it is where dropping the year changes the meaning. APA: “if you cite multiple works by the same author or authors, regardless of the publication years, include the date in every in-text citation to prevent ambiguity.” Their own example is a paper citing both Mohammed and Mahfouz (2017) and Mohammed and Mahfouz (2019). Once two works share an author, the year is the thing telling them apart, and a bare “Mohammed and Mahfouz” has stopped pointing at either.

That same instinct — a citation has to point at exactly one entry — is behind three collisions APA writes separate rules for.

Inside the brackets, there are two smaller rules. If anything else joins the citation in the parentheses, the year takes a comma on both sides: APA’s example is “(see Koehler, 2016, for more detail)”. And when a phrase and a citation share one set of brackets they are separated by a semicolon rather than nested — “(e.g., falsely balanced news coverage; Koehler, 2016)” — because APA does not put parentheses inside parentheses.

Two fields have fixed abbreviations for when a source will not supply them. APA asks for “n.d.” in the in-text citation for a work with no date, and “in press” for one that has been accepted for publication but has not yet been published. The year you do have should match the reference list entry and should stay a year: APA asks for only the year “even if the reference list entry contains a more specific date”, so a source dated 12 March 2020 is still (Author, 2020) in your sentence.

The same two forms, described by somebody who is not APA. Purdue’s writing lab states the rule as a method rather than a format: “when using APA format, follow the author-date method of in-text citation. This means that the author’s last name and the year of publication for the source should appear in the text, like, for example, (Jones, 1998).” And it draws the line this page is built around: referring to an idea needs only author and year, while quoting directly needs the page as well. Two forms, one distinction, and it is about what you did with the source rather than about where the brackets go.

The related searches show where people get stuck. Apa reference page and apa format example are people working on the document rather than the sentence. Apa cover page is the title page, which has its own rules. And apa style and apa citation website are the broadest of all — usually somebody who has been handed a requirement and has not yet been told that APA is an author–date system with two in-text forms, which is the whole of this guide.

Not covered here. It will not paraphrase a rule it has not read on APA’s own pages. A great deal of what circulates about APA is a summary of a summary, and the seventh-edition changes are exactly where that goes wrong.

It will not tell you your department’s preferences. The title page alone has two official versions, and a course picks one.

And it will not rank the citation tools yet. That verdict needs a work with fifteen authors, a report by an organisation, and a source with no date, put through each tool and the errors published. What holds instead is simple: every rule and example on this page is quoted from the APA’s own free style pages.
