HSK 2 Locality Nouns: 左 (zuǒ) and 右 (yòu)
In the HSK 2 syllabus outline, 左 (zuǒ, left) and 右 (yòu, right) are classified as monosyllabic locality nouns (方位名词). Unlike ordinary nouns, single-syllable 左 and 右 do not usually stand alone as the object of 在 (zài) or follow 的 (de); instead, they attach directly to paired nouns or follow directional prepositions like 往 (wǎng) and 向 (xiàng).
弟弟用左手写字。
左 attaches directly to 手 (shǒu, hand) to form 左手 (zuǒshǒu, left hand).
× 书店在银行的右。
For this ordinary location sentence, use 银行的右边 (or 银行右边). Bare 右 after 的 is not the natural conversational form here. This is a recommendation for the pattern, not a claim that bare 左/右 never occur in compact written expressions.
Corrected example: 书店在银行的右边。

What 左 and 右 Do as Locality Nouns
In the user-supplied HSK 2 grammar outline, 左 (zuǒ, left) and 右 (yòu, right) are listed under the word class of nouns (名词) as locality nouns (方位名词). In Mandarin grammar, locality words are divided into monosyllabic (single-syllable) and disyllabic (two-syllable) forms. Recognizing that bare 左 and 右 are monosyllabic locality nouns is essential because modern spoken Mandarin restricts where single-syllable position words can appear.
English speakers use the words "left" and "right" flexibly as adjectives, nouns, and adverbs. In Mandarin, single-character 左 and 右 have a much tighter distribution. You will primarily use them in two high-frequency environments: directly before certain one-syllable nouns (especially paired body parts) and immediately after directional prepositions such as 往 (wǎng, toward) or 向 (xiàng, toward).
Pattern 1: Direct Modification of Paired Nouns
When specifying the left or right member of a natural pair—most commonly body parts like hands, feet, eyes, or ears, as well as sides or wings of a building—左 and 右 attach directly to the noun. Together they form a tight two-syllable word or phrase.
弟弟用左手写字。
左 attaches directly to 手 (shǒu, hand) to form 左手 (zuǒshǒu, left hand).
我的右眼有一点儿不舒服。
右 attaches directly to the single-syllable body-part noun 眼 (yǎn, eye).
Do not insert the structural particle 的 (de) between single-character 左 or 右 and the noun it modifies. Because bare 左 and 右 are bound to this direct-attachment pattern in modern usage, treating them like ordinary descriptive adjectives with 的 sounds unnatural.
× 他用左的手拿杯子。
For “left hand”, use the compound 左手, without 的. 左边的手 describes a hand on the left side in a suitable spatial contrast.
Corrected example: 他用左手拿杯子。
他用左手拿杯子。
左手 is the conventional compound for “left hand”.
Pattern 2: Giving Directions with 往 and 向
The second major role of bare 左 and 右 is to serve as the object of the directional prepositions 往 (wǎng) and 向 (xiàng). This compact structure is the standard way to tell someone which way to walk, turn, or look.
请先往左看，再往右看。
Bare 左 and 右 follow the directional preposition 往 (wǎng) before the single-syllable verb 看 (kàn).
请你向右走五十米。
Bare 右 serves as the object of the directional preposition 向 (xiàng).
Key Contrast and Limits: Bare 左 / 右 vs. 左边 / 右边
The most important boundary for learners is knowing where bare 左 and 右 cannot stand alone. Unlike the monosyllabic locality nouns 上 (shàng, on), 下 (xià, under), and 里 (lǐ, inside)—which attach directly to the end of general nouns (as in 桌子上 zhuōzi shàng, on the table)—bare 左 and 右 do not attach directly to the end of everyday nouns to mean "to the left/right of something." Nor can bare 左 and 右 stand alone as the location object after 在 (zài) or after a reference noun + 的 (de).
- To express an independent location ("on the left/right" or "to the left/right of X"), use the disyllabic forms 左边 (zuǒbian) or 右边 (yòubian).
- To modify an ordinary object that is not a natural pair (such as "the cup on the left"), use 左边的 (zuǒbian de) + noun, not bare 左 + noun.
- Keep bare 左 and 右 in your active toolkit for paired body-part compounds (左手, 右脚, 左眼, 右耳), directional commands (往左, 向右), and fixed four-character or two-character expressions.
× 书店在银行的右。
For this ordinary location sentence, use 银行的右边 (or 银行右边). Bare 右 after 的 is not the natural conversational form here. This is a recommendation for the pattern, not a claim that bare 左/右 never occur in compact written expressions.
Corrected example: 书店在银行的右边。
书店在银行的右边。
右边 is the natural full locality form after the reference bank in this sentence.
Frequently asked questions
Can I attach bare 左 or 右 directly after a noun like 桌子左 (on the left of the table) the way I say 桌子上 (on the table)?
No. While 上 (shàng), 下 (xià), and 里 (lǐ) frequently attach directly to the end of common nouns, bare 左 and 右 do not work this way in everyday Mandarin. Always say 桌子左边 (zhuōzi zuǒbian) or 桌子的左边 (zhuōzi de zuǒbian).
What does it mean when 左 and 右 are combined into 左右 (zuǒyòu)?
When combined into the compound word 左右 (zuǒyòu), it most commonly follows a number or quantity expression to mean "approximately" or "around" (for example, 三点左右, around three o'clock). Keep that compound word distinct from the single-syllable directional uses of 左 and 右 taught in this lesson.
Does this HSK 2 grammar label apply to every test centre today?
The HSK 2 classification for 方位名词：左、右 comes from the 2025-11 revised HSK syllabus outline (marked for 2026-07 implementation). Because test centres and platforms transition on specific schedules, always verify which syllabus edition applies to your booked exam.
