/Ap / आप्

"Ap" is the common name of the feminine affixes /cAp, /TAp and DAp डाप्.

These can appear ONLY after bases ending in a अ.

By ajAdyataSTAp, bases ending in a अ must get /TAp. That ajAdyataSTAp rule is only debarred when some other sUtra enjoins /GI or some other affix (like /Ap or some /GI), therefore no feminines ending in a अ ever keep the a अ — it is invariably deleted when adding /Ap or /GI.

In particular, all words formed with /kta or /zAnac get /Ap when f , and so do all pronouns that end in a अ — because no sUtra enjoins any other feminine affix after these.
