Is the word organiza the same in Brazilian and European Portuguese?

No

While the spelling, grammar, and literal meaning of "organiza" are identical in both variants, the typical usage and the vocabulary surrounding the word differ. In Brazil, "organizar" is frequently used to describe the act of tidying or cleaning physical spaces (e.g., "organizar o quarto"). In Portugal, "arrumar" is the standard verb for tidying or cleaning physical objects and spaces, whereas "organizar" is more strictly reserved for the structural planning of events, information, or systems. Additionally, the nouns often paired with the verb change (e.g., "arquivos" in Brazil vs. "ficheiros" in Portugal).
