Editing Zero copula (section)

===Vietnamese===
Somewhat similar to Chinese, the [[Vietnamese language]] requires the copula {{lang|vi|là}} before nouns in [[Predicate (grammar)|predication]]s but does not use a copula before verbs or adjectives, thus {{lang|vi|Tôi '''là''' sinh viên}} (I am a student) but {{lang|vi|Tôi giỏi}} (I [am] smart). The topic marker {{lang|vi|thì}} may appear before an adjective to emphasize the subject, for example {{lang|vi|Tôi '''thì''' giỏi}} (As for me, I am smart). Many prepositions in Vietnamese originated as verbs and continue to function as verbs in sentences that would use a copula in English. For example, in {{lang|vi|Tôi '''ở''' nhà}} (I am at home), the word {{lang|vi|ở}} may be analyzed as either "to be at" or simply "at". Sometimes, attributive adjectives may follow the verb ''có'' (to have), thus ''Tôi '''(có)''' cao'' is a feasible sentence.
