/sas / सस्

The noun /sas is /tad- m + /su —

tad- तद् m + /su
→ ta त + a अ + /su by tyadAdInAmaH
→ sa- सॱ + /su by tadossa तदोःस
→ !**sas सस्

The final s स् disappears before all consonants by etattadoss... —

sa tatra स तत्र "he's there"

Before vowels it behaves like a normal s स् —

so 'tra सो ऽत्र "he's here"

sa:: uvAca स‌ उवाच "he said"

So we can only hear the s स् before a pause —

uvAca saH उवाच सः "he said"
