Mandarin Noun Suffixes 子, 家 and 员: Things, Experts and Members

By Michael McGettrick and Wee Khang LinUpdated 27 September 2026

Three suffixes, three jobs

A GCSE vocabulary list looks like a wall of unrelated words until you notice how much of it is built the same way. Three suffixes do a disproportionate amount of that building, each with its own job: 子 (zi) turns a root into the everyday word for a physical thing, 家 (jiā) turns a field of expertise into the expert who works in it, and 员 (yuán) turns a role or an organisation into the person who fills it. This structure is on the AQA GCSE specification at both Foundation and Higher tier, and it is one of the cheapest vocabulary gains available: learn the three patterns and a whole shelf of "new" words turn out to be old roots you already know, plus one syllable.

子 (zi): the ordinary-object suffix

子 in this role carries the light, unstressed neutral tone - it is written zi, not zǐ, even though the same character carries a full third tone at the start of a word (as in 子女 (zǐ nǚ), sons and daughters). Stuck onto a one-syllable root, it produces the plain, everyday noun for a physical object or a family member:

  • 桌 (zhuō) + 子 (zi) = 桌子 (zhuō zi) - table, desk
  • 房 (fáng) + 子 (zi) = 房子 (fáng zi) - house, building
  • 儿 (ér) + 子 (zi) = 儿子 (ér zi) - son
  • 孩 (hái) + 子 (zi) = 孩子 (hái zi) - child

Some of these split cleanly into root plus suffix (桌子 (zhuō zi): 桌 (zhuō) on its own is a recognisable root meaning "table"). Others, like 孩子 (hái zi), are best learned as one word: 孩 (hái) barely stands alone in modern speech, so the "suffix" here is really a fossil of an older word-building pattern rather than something you can strip off and reuse. Either way, the practical rule for a learner is the same: when you meet a new one-syllable root for an everyday object, try adding 子 (zi) before assuming the word is something else entirely.

子 also marks a small, casual or everyday object in a handful of other words - 杯子 (bēizi, cup), 本子 (běnzi, notebook) - which is why so many household objects carry it. It is one of the commonest noun endings in everyday Mandarin.

家 (jiā): the expert, the writer, the artist

Add 家 (jiā) to a field of study, a craft or a creative activity and you get the person who is expert in it - much like English -er in "writer" or -ist in "scientist", except 家 (jiā) also carries a note of accomplishment that plain -er does not always have:

  • 作 (zuò) (write) + 家 (jiā) = 作家 (zuò jiā) - writer, author
  • 科学 (kē xué) (science) + 家 (jiā) = 科学家 (kē xué jiā) - scientist
  • 画 (huà) (paint) + 家 (jiā) = 画家 (huà jiā) - painter
  • 音乐 (yīn yuè) (music) + 家 (jiā) = 音乐家 (yīn yuè jiā) - musician

Every one of these describes someone recognised in their field, not just anyone who happens to be doing the activity right now. Someone who paints as a hobby is 喜欢画画的人 (xǐhuan huà huà de rén, someone who likes painting); a 画家 is a painter by trade or reputation. Keep that distinction and you will use the suffix the way native speakers do.

家 is also an ordinary standalone word - "home, family, household" (回家, huí jiā, go home) - and it turns up as a plain root, not a suffix, in words like 国家 (guójiā, country) and 大家 (dàjiā, everyone; its own grammar is covered on the 大家 and 自己 page). Context tells you which job it is doing: after a field of expertise, it is the "-ist" suffix; on its own, it is "home" or "family".

员 (yuán): the person who does the job, or belongs to the group

员 (yuán) attaches to an activity or an organisation and produces the person who carries it out professionally, or who is a recognised member of it:

  • 服务 (fú wù) (serve) + 员 (yuán) = 服务员 (fú wù yuán) - waiter, service assistant
  • 售货 (shòu huò) (sell goods) + 员 (yuán) = 售货员 (shòu huò yuán) - shop assistant
  • 演 (yǎn) (perform) + 员 (yuán) = 演员 (yǎn yuán) - actor, performer
  • 队 (duì) (team) + 员 (yuán) = 队员 (duì yuán) - team member

The range is wider than English -er: it covers paid roles (服务员, 售货员) and unpaid membership alike (队员, and the standalone word 成员, chéngyuán, member). The thread running through all of them is "a person who is officially part of this system", whether or not a wage is involved. When you meet an unfamiliar word ending in 员, a safe first guess is "a person who belongs to or works in the thing named by the rest of the word".

Telling suffix from root

Not every 子, 家 or 员 you meet is doing suffix duty. 国家 (guójiā, country) and 成员 (chéngyuán, member, where 员 is fused with 成 rather than attached to an independent root) both use these characters as ordinary roots or fixed compounds, not as a productive ending you could remove and reattach elsewhere.

The test: strip the character off and check whether what is left still means something close to the whole word.

WordStrip the suffixLeft withSuffix or root?
(zhuō zi)remove (zi)桌zhuō (zhuō) (table)Suffix - the meaning survives
(zuò jiā)remove (jiā) (zuò) (write, do)Suffix - a field, now with its expert
(fú wù yuán)remove 员yuán (yuán) (fú wù) (service)Suffix - a role, now with its holder
(guó jiā)remove (jiā)国guó (guó) (nation - only in compounds)Root - (guó jiā) is one fixed word

When the stripped root does not stand comfortably on its own in everyday speech, treat the whole word as a single vocabulary item rather than hunting for a productive pattern.

Worked examples

  1. ，。 (Tā de fángzi hěn dà, yǒu wǔ ge fángjiān.) - His house is big; it has five rooms. 房 + 子: an ordinary object.
  2. ，。 (Tā shì yǒumíng de zuòjiā, xiěle hěn duō shū.) - She is a famous writer; she has written a lot of books. 作 + 家: expert in a field.
  3. 。 (Cāntīng lǐ de fúwùyuán hěn rèqíng.) - The waiter in the restaurant is very friendly. 服务 + 员: a paid role.
  4. 。 (Wǒmen duì yǒu shí'èr míng duìyuán.) - Our team has twelve members. 队 + 员: group membership, no job attached.
  5. 。 (Tā xiǎng chéngwéi yī míng kēxuéjiā.) - He wants to become a scientist. 科学 + 家: expert in a field of study.

Common mistakes

  1. Reading (zi) with its full tone. As a noun suffix it is neutral-toned zi, not zǐ. Saying the two syllables as zhuō zǐ for 桌子 marks you as reading the character in isolation rather than the word as a unit.
  2. Adding (jiā) to just any activity. 家 (jiā) implies recognised expertise, not casual participation. 我是画家 (wǒ shì huà jiā) (I am a painter) claims a profession; someone who paints occasionally is 喜欢画画的人 (xǐ huan huà huà de rén), not 画家 (huà jiā).
  3. Treating every 员yuán (yuán) word as a paid job. 队员 (duì yuán) and 成员 (chéng yuán) are unpaid memberships; only context (and the base word) tells you whether pay is involved.
  4. Trying to strip (jiā) off (guó jiā) or 员yuán (yuán) off (chéng yuán). Both are fixed words, not root-plus-suffix. If the stripped root does not survive as a normal standalone word, learn the whole thing together.

Frequently asked questions

What does the suffix 子 (zi) do in Mandarin?
子 (zi, unstressed neutral tone in this role) turns a root into the everyday noun for a physical object or a person: 桌 + 子 = 桌子 (zhuōzi, table), 房 + 子 = 房子 (fángzi, house), 儿 + 子 = 儿子 (érzi, son). It is one of the commonest ways Mandarin makes a one-syllable root sound like a complete word.
What is the difference between 作家 (zuòjiā) and just 作 (zuò)?
作 (zuò) alone is a verb root meaning 'to make, to do, to write'; it is not a standalone noun for a person. Add 家 (jiā) and it becomes 作家 (zuòjiā), 'writer' - the person whose profession or expertise is that field. The same pattern gives 科学家 (kēxuéjiā, scientist) from 科学 (kēxué, science) and 画家 (huàjiā, painter) from 画 (huà, to paint).
Does 员 (yuán) always mean a job, like -er in English?
Mostly, but with a wider range than English -er. 员 covers a paid role (服务员 fúwùyuán, waiter; 售货员 shòuhuòyuán, shop assistant) and membership of a group with no job attached (队员 duìyuán, team member; 成员 chéngyuán, member). The common thread is 'a person who is part of this system', whether that system pays them or not.
Is 家 (jiā) always a suffix in Mandarin?
No - 家 is also an ordinary standalone word meaning 'home, family, household' (回家 huí jiā, go home), and it appears as a root rather than a suffix in words like 国家 (guójiā, country) and 大家 (dàjiā, everyone). As a suffix it attaches to a field of expertise or a piece of creative work and means the person who is expert in it: 作家, 科学家, 画家, 音乐家 (yīnyuèjiā, musician).
How do I tell whether 子, 家 or 员 is a suffix or part of the root word?
Strip the character off and check whether what is left still carries the core meaning on its own. 桌子 (zhuōzi) minus 子 leaves 桌 (zhuō), a recognisable root for 'table' (as in 书桌, shūzhuō, desk), so 子 is a suffix. 孩子 (háizi) minus 子 leaves 孩, which barely occurs alone in modern Mandarin, so treat 孩子 as one fixed word to learn rather than root-plus-suffix. When in doubt, learn the whole word first and notice the pattern afterwards.
