How to use it

'là' connects the subject to a noun or noun phrase, often indicating identity, profession, definition, or judgment. Unlike English 'to be', it is not used with adjectival predicates; adjectives usually stand alone as predicates in Vietnamese.

  • 'là' is followed by a noun, noun phrase, or identity description.
  • Adjectives used as predicates do not require 'là'.
  • Beginner-friendly sentence patterns include demonstratives like 'Đây là...' or 'Đó là...'.

Compared with English

Compared with English

In English, both 'He is tall' and 'He is a teacher' use 'is'. In Vietnamese, only noun predicates use 'là'; adjectival predicates do not. For example, 'Anh ấy cao' means 'He is tall' without 'là'.

Common mistakes

Anh ấy là cao.

Anh ấy cao.

'cao' is an adjective; adjectives serve as predicates directly without 'là'.

Tôi sinh viên.

Tôi là sinh viên.

When stating identity or profession, 'là' is usually needed between subject and noun.
