 It is not the case that every noun is only associated with one classifier . Across dialects and speakers there is great variability in the way classifiers are used for the same words , and speakers often do not agree which classifier is best . For example , for cars some people use 部 bù , others use 台 tái , and still others use 辆 ( 輛 ) liàng ; Cantonese uses 架 gaa3 . Even within a single dialect or a single speaker , the same noun may take different measure words depending on the style in which the person is speaking , or on different nuances the person wants to convey ( for instance , measure words can reflect the speaker 's judgment of or opinion about the object ) . An example of this is the word for person , 人 rén , which uses the measure word 个 ( 個 ) gè normally , but uses the measure 口 kǒu when counting number of people in a household , and 位 wèi when being particularly polite or honorific , and 名 míng in formal , written contexts ; likewise , a group of people may be referred to by massifiers as 一群人 ( yì qún rén , " a group of people " ) or 一帮人 ( yì bāng rén , " a gang / crowd of people " ) : the first is neutral , whereas the second implies that the people are unruly or otherwise being judged poorly .
