@fiatjaf  participated in a live to talk about Nostr, on the YouTube channel of the Brazilian @AlexandreCosta, on the occasion, Costa said that he pronounced NOS T R "Nos-tee-arr", so, Fiatjaf just reproduced what Costa said! So that's it! For me, Nostra is very good! 

 See here the exact moment he pronounces "Nos T R" https://youtu.be/2pedWpRcx7Y?si=ZNfnQIT3hrkHfk9U&t=110
