Grammar Rule in 30 Seconds
Always use object pronouns (him, her, me, us, them) after the verb 'let' when giving a command or permission.
- Use 'him' after let: 'Let him go' (not 'Let he go').
- Use 'us' for suggestions: 'Let us (Let's) start the meeting.'
- Avoid 'he' unless it's a very rare archaic quote like 'Let he who is without sin...'
Overview
let he and let him is a perfect example of this system in action. The rule is absolute and consistent: you must always use an object pronoun after the verb let.let him, let me, let her, let us, and let them are correct, while constructions such as let he, let I, let she, let we, and let they are grammatically incorrect in modern standard English.let's grammatical identity. Let is a transitive verb, meaning it requires a direct object to receive its action of 'allowing' or 'permitting'. Furthermore, it belongs to a special class of causative verbs that follow a unique pattern: verb + object + bare infinitive (the base form of a verb without to).let + object + base verb pattern. By understanding the 'why' behind the rule, you'll be able to apply it confidently and correctly in all contexts.How This Grammar Works
let him is correct, we need to explore three foundational concepts: pronoun case, transitivity, and causative verbs. These principles work together to dictate the sentence structure.- Subject Pronouns (
I,you,he,she,it,we,they) perform the verb's action. They are the subject of the sentence. For example, inHe called the office,heis the one performing the action of calling.
- Object Pronouns (
me,you,him,her,it,us,them) receive the verb's action or follow a preposition. InThe manager saw her,heris the one being seen; she is the object of the verbsaw.
I | me | I read the report. | She emailed me. |he | him | He designed the logo. | The team chose him. |she | her | She leads the project. | We depend on her. |we | us | We will attend. | They invited us. |they| them | They agreed. | The news surprised them. |hit, see, buy, and write are transitive. You don't just hit; you hit the ball. You don't just buy; you buy groceries.Let is a classic transitive verb. Its meaning, 'to permit', requires an object—the person or thing being permitted. A sentence like The guard let... is incomplete.Let who? Let what?The answer to that question is the direct object, and that object must be in its objective form. This is why we need
him, her, or us to complete the thought: The guard let him pass.Let is also a causative verb, a category that includes make and have. Causative verbs indicate that the subject 'causes' the object to perform an action. These verbs are special because they follow a specific and rigid pattern: Causative Verb + Object + Bare Infinitive.to. Examples include go, see, do, be, and decide. Most English verbs that are followed by another verb require the to-infinitive (want to learn, need to stop), but causatives are a major exception.let commands this exact sequence. Compare let with a more standard verb like allow:The company let him take a vacation.(Causativelet+ objecthim+ bare infinitivetake)The company allowed him to take a vacation.(Standard verballow+ objecthim+to-infinitiveto take)
let him go is that let is a transitive, causative verb that requires an object pronoun (him) followed immediately by a bare infinitive (go).
Formation Pattern
let is consistent and predictable, which makes it easy to master once you internalize the components. Every correct sentence using let in this way will follow this structure.
Let + Object (Pronoun or Noun) + Base Verb (Bare Infinitive)
Let: This is the unchanging verb that begins the construction. In commands and suggestions, it does not change form. (The simple present form lets, as in He lets his dog run, is different and refers to a habitual action, not a specific command or proposal).
Object: This slot must be filled by a word in the objective case. This can be an object pronoun or a noun/noun phrase. A subject pronoun is never correct here.
me, you, him, her, it, us, them.
the doctor, my colleagues, the system, a new employee.
Base Verb (Bare Infinitive): This is the infinitive form of the verb without to. It does not change based on the subject or tense. It is always the simple, un-conjugated form. Examples: be, have, try, finish, speak.
to-infinitive) |
Let me explain. | *Let I explain. | *Let me to explain. |
Let him decide. | *Let he decide. | *Let him to decide. |
Let her go. | *Let she go. | *Let her to go. |
Let us try. / Let's try. | *Let we try. | *Let us to try. |
Let them finish.| *Let they finish. | *Let them to finish. |
Please let the students ask questions. (Object is noun phrase the students, base verb ask)
Did you let the delivery driver inside? (Object is noun phrase the delivery driver, base verb inside is part of phrasal verb let inside)
Don't let that minor issue become a major problem. (Object is noun phrase that minor issue, base verb become)
let is followed by a receiving object, which is then followed by the base form of the action verb.
When To Use It
let + object + base verb construction is a workhorse in English, used across various situations to express permission, make suggestions, or issue commands. Understanding its different functions will improve your communicative precision.- 1Granting Permission or Allowing an Action
let. It signifies that the subject is giving consent or removing an obstacle for the object.Her parents let her stay out late on weekends.(They permit her to do so.)The software won't let me save the file.(The software is not permitting the action.)After I presented my report, the CEO let me take the lead on the project.(Formal permission was granted.)
- 1Making Suggestions or Proposals (with
Let's)
let's (let us) is one of the most common ways to propose a collective action that includes the speaker. It's inclusive and collaborative.It's getting late. Let's go home.(A suggestion for the group.)Let's not make any assumptions until we have all the data.(A negative proposal, suggesting inaction.)Let's schedule a meeting for next week to discuss this further.(A common professional suggestion.)
- 1Issuing Mild Commands or Imperatives
let often serves as a command directed at the listener, but concerning a third party. It can be softer than a direct command.- A child is interrupting his father. The mother says to the child:
Let him speak.(The command is to the child, allowing the father to speak.) Let them figure it out for themselves. They need to learn.(A command to not interfere.)- The phrase
Let it gois a famous example, advising someone to stop dwelling on an issue.
- 1Formal Declarations and Set Phrases
let can be used to make a solemn declaration. These are often fixed expressions.Let the record show that the defendant was not present.(A phrase used in legal settings.)Let it be known that from this day forward, all employees will receive a bonus.(A formal announcement.)- The historical quote,
Let them eat cake,
uses this structure to issue a dismissive, royal-sounding command.
Common Mistakes
let because its pattern is an exception to more common grammatical rules.- 1Using a Subject Pronoun instead of an Object Pronoun
*Let we see. is incorrect because we is a subject pronoun. The verb let demands an object.- Why it happens: Learners may mentally connect the pronoun to the second verb (
weare the ones who willsee), thinking of it as the subject of that second action. However, grammatically, the pronoun is the object of the first verb,let. - Correction:
Let us see.orLet's see.
- 1Using a
to-infinitive instead of a Bare Infinitive
*Please let me to know is a very common error.- Why it happens: Most English verbs that precede another verb use the
to-infinitive (need to know,want to know,plan to know). Learners over-apply this dominant pattern to the exceptional causative verbs. - Correction:
Please let me know.Remember thelet-make-havegroup all use the bare infinitive.
- 1Incorrect Verb Agreement on the Second Verb
*Let him tells you or *She lets me goes sometimes occur.- Why it happens: Learners try to apply standard subject-verb agreement rules to the second verb, conjugating it for the third person (
he tells,she goes). - Correction: The
let + object + verbstructure 'freezes' the second verb in its base form. It is always the bare infinitive, regardless of the object.Let him tell you.She lets me go.
- 1Confusion with Compound Objects
*My manager let my colleague and I leave early.- Why it happens: The presence of a noun (
my colleague) can obscure the fact that the pronounIis still in the object position. - Correction: Use the 'isolation test'. Remove the other person from the sentence. You would never say
*My manager let I leave early.You would sayMy manager let me leave early.Therefore, the correct form must beMy manager let my colleague and me leave early.
- 1Confusing
Let'sandLets
Let's (with an apostrophe) is a contraction of let us and is used for proposals. Lets (with no apostrophe) is the third-person singular present tense of the verb let.- Proposal:
Let's eat.(Let us eat.) - Habitual Action:
He lets his cat eat at the table.(He permits his cat to do this regularly.)
Real Conversations
Textbook examples are clean, but real-world English is often faster and more condensed. Here’s how you’ll see and hear the let structure used in everyday life.
- In a Work Slack/Teams Channel:
> Hey team, let me know if you have any questions about the Q3 report. I'll be online all day.
- In a Text Message Conversation:
> Friend 1: Should I reply to his weird message?
> Friend 2: Nah just let it be. don't give him the attention.
- In a Casual Spoken Conversation:
>
My son wanted to join the band, so of course, we had to let him buy a drum set. Our poor neighbors!
- On Social Media (e.g., a comment on a post):
> People are really complaining about a free update? Wow. Let them be miserable, I guess.
- In a Formal Meeting:
> "Before we conclude, let's not forget to thank Sarah for her hard work on this initiative."
Notice how in informal contexts like texting, capitalization and even whole words (us in let's) might be dropped, but the core grammatical structure (let + object pronoun) remains intact.
