How to Say "unfamiliar" in Spanish
The most common Spanish word for “unfamiliar” is “desconocido” — use 'desconocido' when referring to a place, person, or thing that is completely unknown and has not been encountered before..
desconocido
des-koh-noh-SEE-doh/des.ko.noˈsi.ðo/

Examples

We went to a completely unknown beach.

The origin of the signal continues to be unknown.

Making it Match
Like most Spanish adjectives, 'desconocido' must change its ending to match the noun it describes: use '-a' for feminine nouns (la casa desconocida), '-os' for masculine plural nouns, and '-as' for feminine plural nouns.
Forgetting Agreement
Mistake: “Vi una persona desconocido.”
Correction: Vi una persona desconocida. (Since 'persona' is a feminine noun, the adjective must end in -a.)
extraños
Examples

We found some strange objects in the old closet.
nuevos
NWAY-vohs/ˈnweβos/

Position Changes Meaning
When 'nuevos' is placed after the noun (e.g., 'amigos nuevos'), it often means 'newly acquired' or 'newly changed.' If placed before ('nuevos amigos'), it usually means 'just another set of friends.'
