How Spanish, English and Chinese omit subject pronouns in finite clauses.
Compare languages
Pro-drop languages allow subject omission when recoverable from context. Spanish consistently drops subjects. English requires subjects except in imperatives. Chinese drops subjects freely in context.
Overview
Pro-drop (pronoun-dropping) is the omission of subject pronouns when they are recoverable from context.
- Spanish: Consistent pro-drop language. Rich verb inflection marks person and number. Subjects are omitted by default; explicit pronouns signal emphasis or contrast.
- English: Non-pro-drop language. Almost no verbal inflection for person. Subjects are mandatory in finite clauses. Exceptions: imperatives, coordinated clauses, and short answers.
- Chinese: Discourse pro-drop. No verbal inflection, but subjects are frequently omitted in context when recoverable from prior discourse.
Spanish
Null subject with rich inflection
The verb ending indicates the subject:
- (Yo) hablo. (I speak. — -o = 1st person)
- (Tú) hablas. (You speak. — -as = 2nd person)
- (Él/Ella) habla. (He/She speaks. — -a = 3rd person)
- (Nosotros) hablamos. (We speak. — -amos = 1st plural)
- (Vosotros) habláis. (You all speak. — -áis = 2nd plural)
- (Ellos/Ellas) hablan. (They speak. — -an = 3rd plural)
When explicit pronouns are used
Emphasis:
- Yo sí quiero ir. (I DO want to go.)
- Tú no entiendes. (YOU don’t understand.)
Contrast:
- Él vino, pero ella no. (He came, but she didn’t.)
Clarity (same person, different referents):
- Juan dijo que él vendría. (Juan said that HE [Juan, not someone else] would come.)
Weather and impersonal (no subject)
- Llueve. (It’s raining.)
- Nieva. (It’s snowing.)
- Hace frío. (It’s cold.)
- Es tarde. (It’s late.)
Coordinated clauses
- Juan vino y (él) se fue. (Juan came and left.)
- María estudia y (ella) trabaja. (María studies and works.)
Subordinate clauses
- Creo que (él) está aquí. (I think he’s here.)
- Dice que (ella) vendrá. (She says she’ll come.)
English
Mandatory subjects
English requires explicit subjects in finite clauses:
- ✅ I speak English.
- ❌ Speak English. (ungrammatical as a statement)
Exceptions
Imperatives:
- Come here! (you understood)
- Sit down! (you understood)
Coordinated clauses (same subject):
- John came and (he) left. (he optional)
- She read the book and (she) wrote a review.
Short answers:
- Are you coming? — Yes. / No. (I am / I’m not — understood)
- Who broke it? — John. (John broke it — understood)
Diary style / informal registers:
- Went to the store. Bought milk. (informal, telegraphic)
Infinitival and participial clauses:
- To err is human. (no subject in infinitive)
- Reading is fun. (no subject in gerund)
Expletive subjects
English requires a dummy subject when there is no real subject:
- It is raining. (it = expletive, no meaning)
- It is late.
- There is a book on the table. (there = expletive)
Pro-drop in early child English
Children learning English sometimes omit subjects:
- Want cookie. (adult: I want a cookie.)
This is a developmental stage, not grammatical adult English.
Chinese
Discourse pro-drop
Chinese frequently drops subjects in conversation when context is clear:
-
A: 你去哪儿？(Where are you going?)
-
B: (我)回家。((I) go home.)
-
A: 他来了吗？(Did he come?)
-
B: (他)来了。((He) came.)
Topic-drop
Chinese can drop both subject and topic when context is clear:
- (这件事)我不知道。((This matter) I don’t know.)
- (这本书)已经读完了。((This book) already finished reading.)
No inflectional recoverability
Unlike Spanish, Chinese verbs do not mark person:
- 说 = I speak / you speak / he speaks / we speak
Subject drop depends entirely on discourse context, not verbal inflection.
Coordinated clauses
- 他来了，(他)又走了。(He came and (he) left again.)
Weather expressions
No subject required:
- 下雨了。(It’s raining.)
- 下雪了。(It’s snowing.)

Spanish speakers learning English: Speak English → I speak English (subject required)
-
English speakers learning Spanish: Yo hablo español in every sentence → (Yo) hablo español (drop yo unless emphatic)
-
English speakers learning Chinese: 下雨了 is fine, but in written Chinese, subjects may be required for clarity
-
Chinese speakers learning English: Is raining → It is raining (expletive subject required)
