In Japanese, the subject or object of a sentence need not be stated if it is obvious from context. As a result of this grammatical permissiveness, there is a tendency to gravitate towards brevity; Japanese speakers tend to omit pronouns on the theory they are inferred from the previous sentence, and are therefore understood. In the context of the above example, "hana-ga nagai" would mean "noses are long," while "nagai" by itself would mean "[they are long." A single verb can be a complete sentence: "Yatta!" () "/ we / they / etc did In addition, since adjectives can form the predicate in a Japanese sentence (below), a single adjective can be a complete sentence: "Urayamashii!" () "[I'm jealous it!".
