Etymology
Terán is generally treated as a Spanish surname taken from a place-name, likely referring to someone who came from a locality called Terán or a closely related form. The older sources here list it among Spanish surnames but do not give a full derivation, so the safest reading is locational rather than occupational or descriptive. The accent-marked form Terán is the conventional Spanish spelling, while Teran is a simplified form used in contexts without diacritics.
History
Terán has long been used in Spanish-speaking regions and remains especially familiar in Spain and the Hispanic Americas. In modern records it often appears without the accent, as Teran, especially in the United States.
