What is 81 in Spanish? Cardinal and Ordinal Forms

In Spanish, the cardinal form of eighty-one is "ochenta y uno" (IPA: /oˈtʃenta i ˈu.no/). This number is used to count objects or people. The ordinal form for eighty-first is "octogésimo primero" (IPA: /oktaˈxesimo ˈpɾimeɾo/) and it indicates the position of something in a sequence.

To help non-native speakers pronounce these numbers correctly, here are some pronunciation tips:
