Mandarin Demonstratives: 这 (zhè) and 那 (nà)
A Spanish learner pointing at things has to juggle este, esta, estos, estas, and then the whole set again for 'that'. A Mandarin learner gets two words and keeps them forever: 这 (zhè) for what is near the speaker, 那 (nà) for what is not. No gender, no case, no agreement of any kind. The demonstrative you learn on day one is the demonstrative you use in year ten.
The pattern: demonstrative + measure word + noun
What Mandarin asks for instead of agreement is a measure word in the slot between the demonstrative and the noun. The general-purpose measure word is 个 (gè), and the beginner pattern is:
(zhè) / (nà) + (gè) + noun
- 这个人 (zhège rén) - this person
- 那个人 (nàge rén) - that person
- 这个先生 (zhège xiānsheng) - this gentleman
- 那个事 (nàge shì) - that matter
The measure-word slot is not decoration. 这人 (zhè rén) with nothing in the slot is not the standard form; the phrase wants 这个人 (zhège rén). Later chapters introduce the measure words particular nouns prefer, but 个 (gè) is the safe default and the one to automate now.
Plurals: 些 (xiē) replaces the measure word
To point at more than one thing, you do not pluralise the noun (Mandarin nouns do not change) and you do not pluralise the demonstrative. You swap the measure word for 些 (xiē), which means an unspecified amount:
- 这些人 (zhèxiē rén) - these people
- 那些人 (nàxiē rén) - those people
- 这些事 (zhèxiē shì) - these matters
- 那些事 (nàxiē shì) - those matters
That is the whole system: four shapes. 这个 (zhège), 那个 (nàge), 这些 (zhèxiē), 那些 (nàxiē), each followed by an unchanging noun.
Standing alone
Before 是 (shì), the bare demonstrative points at a whole thing or situation, no measure word needed:
- 这是我先生。(Zhè shì wǒ xiānsheng.) - This is my husband.
- 那是谁?(Nà shì shéi?) - Who is that?
Near and far is the speaker's call
这 (zhè) covers what is close to the speaker in space or time; 那 (nà) covers everything else, including English's 'it was that year' remoteness in time. If you are holding it, standing next to it, or in the middle of it, reach for 这 (zhè). If you are pointing across the room, across the street, or back into last year, reach for 那 (nà). When in doubt, Mandarin speakers lean on 那 (nà) more than English speakers lean on 'that', so the safe guess is the far one.
