Here's why:
* "Portuguese" refers to the language, people, or things related to Portugal.
* In Italian, you would use the appropriate term depending on the context:
* Language: *Portoghese*
* People: *Portoghesi* (plural), *Portoghese* (singular)
* Things: *Portoghese* (adjective, e.g., *vino portoghese* - Portuguese wine)
Therefore, there is no single Italian word that encompasses all meanings of "Portuguese". You need to use the specific term that fits the context.
