Is portuguse Spanish

Answer 1

Portuguese is similar to Spanish, as Spanish is similar to Italian. All three languages are based in Latin. The languages are close enough that if you know one, you can probably get by in another, but they'll think you're a barbarian.

Answer 2

'Portugués' if the person in question is male, or 'Portuguesa' if female, may be Spanish equivalents of 'Portuguese'.

The masculine adjective/noun 'portugués' becomes 'portugueses' when there's more than one Portuguese male. The feminine adjective/noun 'portuguesa' becomes 'portuguesas' when there's more than one Portuguese female. But the masculine plural 'portugueses' is used when there's a mixed group of Portuguese females and males.

The words in the example respectively are pronounced 'pohr-too-GHEHS' and 'pohr-too-GHEH-sah'.

Answer 3

No, Portuguese and Spanish are different languages. They are somewhat similar, but the differences are big enough so that a Spanish-speaking person can't understand almost any Portuguese (and vice-versa), unless he specifically learned it.
