Grammar Rule in 30 Seconds
Always use object pronouns like 'her' after the verb 'let' because 'let' acts on the person.
- Use 'her' (object), never 'she' (subject) after let. Example: 'Let her finish.'
- This applies even with compound objects. Example: 'Let her and me talk.'
- The verb following the pronoun is always the base form. Example: 'Let her go.'
Overview
let she and let her tests a core principle of English grammar: the difference between subject pronouns and object pronouns. The rule is absolute: the verb let must always be followed by an object pronoun. Therefore, let her is always correct, and let she is always incorrect. This isn't an exception to memorize; it's a fundamental aspect of how verbs and objects function in English.let is a verb of permission. It means to allow or permit something to happen. In any sentence, the person or thing that *receives* the action of a verb is the object.let, the person receiving the permission is the object. For example, in the phrase Let her speak, the pronoun her is the object of the verb let. It is her who is being permitted to do the action.I, you, he, she, it, we, they) are the 'doers' of an action—they perform the verb. Object pronouns (me, you, him, her, it, us, them) are the 'receivers' of an action. Because let requires a receiver for its permission, you must use an object pronoun.How This Grammar Works
let her is correct, we need to examine the function of let within a sentence. The verb let has two key properties: it is both a transitive verb and a causative verb, and both properties require it to be followed by an object.see is transitive.I see; the sentence feels incomplete. You must say what you see: I see a car. The verb let works the same way. A sentence like The manager let is nonsensical.The manager let him leave early. That pronoun, him, is the direct object of let.let is a causative verb. Causative verbs express that the subject of the sentence causes, permits, or makes someone else perform an action. The most common causative verbs are make, have, and let.Let her explain the situation.her is the one doing the explaining. In that sense, her is the logical agent (or 'doer') of the verb explain.let, takes priority. The pronoun her is the direct object of let—it is the one being permitted. English grammar demands that a direct object must be in the object case.let is more important than the logical role as the subject of explain.let is followed by the base form of a verb without to (e.g., go, do, be). This is a unique pattern. Contrast let with a similar verb like allow:let | let + object + bare infinitive | They let her go. | Correct |allow | allow + object + to-infinitive | They allowed her to go. | Correct |let | let + object + to-infinitive | They let her to go. | Incorrect |let + object + bare infinitive, is a cornerstone of English syntax. The object pronoun is an inseparable part of the structure, bridging the act of permission (let) and the resulting action (go).
Formation Pattern
let is consistent and predictable. Once you learn the pattern, you can apply it to any pronoun or noun. The core formula is:
Let + Object + Bare Infinitive (Verb)
Let: This is the verb of permission. It's an irregular verb. In the imperative (commands or suggestions), it remains Let. In the present tense, it is let for most subjects but lets for the third-person singular (he, she, it). The past tense is also let.
Let me see.
She lets her children play outside.
Yesterday, he let me borrow his notes.

When To Use It
let construction is versatile and appears in many different situations, ranging from casual suggestions to formal permissions. Mastering its contexts will make your English sound more natural and precise.us, usually in its contracted form Let's. This is the standard way to make an inclusive suggestion in English, inviting others to join an activity.Let's get some coffee before the movie starts.(A suggestion to a group)Let's not worry about that until tomorrow.(A suggestion to avoid an action)It's a difficult problem. Let's think it through carefully.
let: to permit or allow. It's used frequently by people in positions of authority (parents, managers, officials) but also between peers.My manager let me leave work early today.(Permission was given)Her parents won't let her go to the concert.(Permission is denied)The guard let them pass after they showed their IDs.
Let me... or Let him... can be a softer, more polite alternative to a direct imperative. It signals an intention to do something helpful.That bag looks heavy. Let me help you with it.(An offer)Please, let her finish speaking.(A polite instruction to others)Let me check the schedule and I'll get back to you.(A way of stating a next step)
let is to express a lack of resistance or an acceptance of a situation, often one you cannot change. This implies a philosophical or passive stance.He can think what he wants. I let him believe it.(I don't intervene)If they want to complain, let them.(It doesn't bother me)- The famous Beatles song
Let It Beis a perfect example, meaning 'accept the situation as it is'.
Common Mistakes
letlet.- Incorrect:
My friend and I wanted to start, so the teacher let ~~we~~ begin. - Why it's wrong:
weis the object oflet, so it must be in the object case. The correct pronoun isus. - Correct:
My friend and I wanted to start, so the teacher let us begin.
- Incorrect:
When he finished his presentation, the boss let ~~he~~ sit down. - Why it's wrong:
heis the receiver of the permission fromlet, so the object pronounhimis required. - Correct:
When he finished his presentation, the boss let him sit down.
to-infinitive Instead of the Bare Infinitiveto (e.g., I want to speak). Learners forget that let is one of the special causative verbs that breaks this pattern.- Incorrect:
I don't let my kids ~~to watch~~ too much TV. - Why it's wrong: The pattern is fixed:
let+ object + bare infinitive. - Correct:
I don't let my kids watch too much TV. - Quick Tip: If you are tempted to use a
to-infinitive, see if you can substituteallow. Ifallow... toworks, thenlet...(withoutto) is likely the correct alternative. For example,I don't allow my kids to watch TVis also correct.
Let's and LetsLet's: A contraction ofLet us. It is *only* used for making suggestions.Let's go.(Means: I suggest that we go.)Lets: The third-person singular present tense of the verblet. It is used afterhe,she,it, or a singular noun.She lets her dog run in the park.(Means: She permits her dog to run.)
- Incorrect:
Lets have a meeting tomorrow.(This should be a suggestion.) - Correct:
Let's have a meeting tomorrow. - Incorrect:
My phone plan let's me use data in other countries.(This is about permission.) - Correct:
My phone plan lets me use data in other countries.
Real Conversations
The let structure is extremely common in all forms of modern English. You will hear and see it constantly in everyday life. Here’s how it appears in different contexts, showing its natural and practical use.
In Texting and Social Media:
Usage here is often brief and direct. The imperative form is very common.
- Person A: I can't figure out this new app.
Person B: let me see. i use it all the time
- Person A: Ugh I'm so bored
Person B: let's do something tn (tn = tonight)
- Post Caption: My sister let me borrow her new jacket. What do we think?
At Work (in Emails, Slack, or Meetings):
In professional settings, let is standard for polite offers, instructions, and follow-ups. Let me know is one of the most common phrases in business English.
- Email: The draft is attached. Let me know if you have any feedback.
- Slack: Let's table this discussion until the weekly sync.
- Meeting: "Before we move on, let's let him finish his point."
In Casual, Spoken Conversation:
Here, you'll hear let used to talk about permission, tell stories, and manage interactions smoothly.
-
My dad let me drive his car for the first time last weekend. I was so nervous!
- "Just let it go. It's not worth getting upset about."
- "Hang on, let me find my keys... okay, I'm ready now."
Cultural Observation:
The phrase Let me... (e.g., Let me ask..., Let me think...) is often used not to ask for permission, but as a discourse marker to signal a shift in thought or to politely take a turn in the conversation. It softens the action. Instead of just starting to think silently, saying Let me think communicates the process to the listener, making the interaction smoother.
Quick FAQ
Let she go would be correct?No, absolutely never. Because let requires an object, the pronoun following it must be in the object case (her). Let she is grammatically impossible in standard English.
let's and lets again?Let's is a contraction of let us and is only used to make a suggestion (e.g., Let's eat). Lets is the third-person singular form of the verb to let (e.g., He lets his dog off the leash). The apostrophe is the key difference.
let her go but allow her to go?This is because let is a special causative verb that uses a bare infinitive (the verb without to). Other verbs of permission, like allow and permit, follow the more common pattern of using a to-infinitive. It's a specific rule tied to the verb let.
let in the past tense?Let is an irregular verb. Its simple past tense form is also let. You can distinguish it from the present tense by the context. For example: Yesterday, my boss let me leave early. The word Yesterday tells you this is a past action.
let in a passive sentence?It's possible but very rare and often sounds unnatural. For example, She was let go from her job (meaning she was fired) is a common idiom. However, in most cases, we use a passive form of allow instead. For example, instead of He was let to enter, we would say He was allowed to enter.

用 'Me' 测试法
me 或 I 替换。你会发现 Let me go 听起来很对，而 Let I go 听起来就很奇怪。这个小测试能帮你记住，'let' 后面需要宾格代词，所以 her, him, them 也是对的。Let's vs. Lets
She lets her cat outside（她让她的猫出去）。
听起来更自然
let her 连读，听起来像 letter。比如 We should letter decide其实是
We should let her decide（我们应该让她来决定）。你不用这样写，但听别人说的时候可以留意一下！
直接与礼貌
let me... 表达请求是很礼貌的。但如果你说 Let him do it（让他来做），根据你的语气，可能会听起来有点命令的感觉。在更正式或敏感的场合，人们可能会选择更委婉的说法，比如
Would it be okay if he...（他来做可以吗？）或者
Could we allow him to...（我们能允许他来做吗？）。
