in colloquial speaking, usage of a pronoun is optional. Even so, sentences with a null subject are used more frequently than sentences with a subject. In some cases, it is even necessary to skip the subject to create a grammatically correct sentence. Chinese Most varieties of Chinese tend to be non-null-subject. Verbs in Chinese languages are not conjugated, so it is not possible to determine the subject based on the verb alone. However, in certain circumstances, most Chinese varieties allow dropping of the subject, thus forming null-subject sentences. One of the instances where the subject would be removed is when the subject is known. Below is an example in Mandarin: The above example clearly shows that a speaker could omit the subject if the doer of the verb is known. In a Chinese imperative sentence, like the first text, the subject is also left out. Galician In Galician, as in Spanish, Portuguese, Catalan, etc., the subject is also encoded in the verb conjugation. Pronoun use is not obligatory. (Nós) Imos á praia: We go to the beach.

(Eu) Necesito axuda: I need help. (El) Está no seu cuarto: He is in his bedroom. (Ela) Está cansada: She is tired. In Galician, one may choose whether to use the subject or not. If used in an inclined tone, it may be seen as an added emphasis; however, in colloquial speaking, usage of a pronoun is optional. Even so, sentences with a null subject are used more frequently than sentences with a subject. In some cases, it is even necessary to skip the subject to create a grammatically correct sentence. Modern Greek Hebrew Hebrew is considered a partially null-subject language, as demonstrated by the following example: Subjects can usually be omitted only when the verb is conjugated for grammatical person, as in the third-person plural in the example above. In Hebrew one can also construct null-subject sentences as in the Latin and Turkish language examples: "We/you/they are going to the beach" can be expressed as "holkhim la-yam" (הולכים לים), lit. "Are going to the beach." This is truly a null-subject construction. As in Spanish and Turkish, though, Hebrew conjugates verbs in accordance with specific pronouns, so "we went to the beach" is technically just
