dik-pUrva-padAd a-saJjJAyAJ JaH

दिक्पूर्वॱपदादॱसंज्ञायां ञः ONPANINI 42107

When a compound has a /diz- ibc, add the /samAsAnta /Ja, but not when a tag.

This debars the default /aN'' from .

According to taddhitArthott..., we may compound together pUrvAyAM zAlAyAm पूर्वायां शालायाम् like this —

pUrvAyAM zAlAyaM yo bhavati पूर्वायां शालायं यो भवति
→ /pUrva- + zAlA- शालाॱ + /Ja
→ !**pUrvazAla- पूर्वशालॱ "he who is in the eastern hall"

What about the f ?

As this /Ja has no /Tit, it gets /Ap by ajAdyataSTAp.

pUrvazAlA- पूर्वशालाॱ "she who is in the eastern hall"

Why does this sUtra have dik-pUrva-padAt दिक्पूर्वॱपदात्. Looks like dik-pUrvAt दिक्पूर्वात् would have worked fine.

Candravasu sez that this is to prevent the sUtra from applying to /diz- itself, in compounds like

/diz- + gajAs गजास् → !**diggajAs दिग्गजास् "the elephants of the quarters".
