"Ninapenda nchi za baridi"

Translation: I like cold countries

[s.rombaut]

Why not just "nchi baridi"?

[Gazelle1596]

baridi itself is "cold" as the noun;
"cold" as adjective is "-a baridi" (I guess in casual speech you can hear both.)

[RudolfJan]

Don't really know, but for me it helps to determine that the plural form is meant.
