From Wiktionary: https://en.wiktionary.org/wiki/abacaxi
I once read that in almost all languages except English, pineapple is something like ananas, nanasi, etc.
Not all, but many. Spanish, for example, has piña, and Catalan has pinya. Japanese uses "painappuru" (an obvious English loanword.) Several people above mentioned the more common Brazilian Portuguese "abacaxi", although "ananás" also exists and is common in Portugal. Most languages use "ananás" or something similar to it.
