Vaginal fornix
superior portions of the vagina
The fornices of the vagina (sing.: fornix of the vagina or fornix vaginae) are the superior portions of the vagina, extending into the recesses created by the vaginal portion of cervix. There is an anterior fornix, a posterior fornix, and two lateral fornices. The fornices vary in shape and size, with the posterior fornix being the largest. The word fornix is Latin for 'arch'.
Sexuality
During sexual intercourse in the missionary position, the tip of the penis may reach the anterior fornix, while in the rear-entry position it may reach the posterior fornix.
The anterior fornix is also called the a-spot, an analogue to the g-spot (Gräfenberg spot), which is closer to the vaginal opening, and also on the anterior side of the vagina.

Begin with the source’s own compact description: “Vaginal fornix” is superior portions of the vagina. The dossier treats that line as a proposition to test through Vaginal, fornix and superior, not as a finished interpretation.
Why this record matters
The phrase “superior portions of the vagina” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 10, 2026. The linked authority identifier is Q1659799. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1264, 1918 and 2016.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
