Let-he در مقابل I-know: تفاوت چیست؟
Grammar Rule in 30 Seconds
Use object pronouns (him/her/them) after 'let', but subject pronouns (he/she/they) when they are the main subject of a verb like 'know'.
- Always use 'him', 'her', or 'them' after 'let' (e.g., 'Let him speak').
- Use 'he', 'she', or 'they' before 'know' (e.g., 'He knows the answer').
- Never say 'Let he' or 'Him knows' in standard modern English.
مرور کلی
let است. در زبان فارسی، ما ساختار متفاوتی داریم. در فارسی، ضمیرها در نقش فاعلی و مفعولی معمولاً تغییر شکل نمیدهند (مثلاً «من» هم در نقش فاعل و هم در نقش مفعول به کار میرود، البته با اضافه شدن «را» در نقش مفعولی).let یک فعل متعدی (Transitive Verb) است. این یعنی این فعل حتماً به یک مفعول نیاز دارد تا عمل «اجازه دادن» بر روی آن انجام شود. وقتی شما میگویید Let me go، کلمه me مفعول این جمله است.Let I go) که از نظر دستوری کاملاً غلط است. درک این نکته که let همیشه به مفعول نیاز دارد، کلید حل این مشکل است. این موضوع در محیطهای کاری، دانشگاهی یا حتی در مکالمات دوستانه در کافههای تهران بسیار کاربردی است.I, he, she, we, they) و مفعولی که پذیرنده کار است (me, him, her, us, them). در زبان فارسی، ما چیزی به نام «ضمیر مفعولی مجزا» (مانند him در برابر he) نداریم.I saw him و He saw me.let به معنای «اجازه دادن» است. چون این فعل یک عمل را بر روی شخصی اعمال میکند، آن شخص باید به صورت ضمیر مفعولی ظاهر شود. به جدول زیر توجه کنید:let + مفعول، فعل بعدی باید به صورت «شکل پایه» (Base Form) بیاید، یعنی بدون to. مثلاً نمیگوییم Let him to go بلکه میگوییم Let him go. این ساختار در انگلیسی بسیار رایج است و در کنار فعلهای دیگری مثل make یا see نیز دیده میشود.- Subject (فاعل): کسی که اجازه میدهد (مثلاً
My boss,She,They). - let(s): فعل اصلی که اگر فاعل سوم شخص مفرد باشد،
sمیگیرد. - Object Pronoun (ضمیر مفعولی): کسی که اجازه میگیرد (
me,him,her,us,them). - Base Verb (فعل پایه): کاری که انجام میشود (بدون
to).
I let him finish his work. |She lets me sit here. |They let us play in the yard. |- 1اجازه دادن یا ندادن: وقتی میخواهید بگویید به کسی اجازه انجام کاری را میدهید. مثال:
My manager lets me work from home(مدیرم به من اجازه میدهد از خانه کار کنم). - 2پیشنهاد دادن (
Let's): این در واقع مخففLet usاست. وقتی میخواهید پیشنهادی برای گروه بدهید. مثال:Let's go to the cafe(بیا بریم کافه). - 3درخواست مودبانه: استفاده از
Let meبرای اینکه مودبانه اجازه بگیرید کاری را انجام دهید یا کمکی بکنید. مثال:Let me help you with your bags(اجازه بدهید در حمل کیفها به شما کمک کنم). - 4ایجاد موقعیت: گاهی برای توصیف یک وضعیت به کار میرود. مثال:
Don't let the stress affect your exam(اجازه نده استرس روی امتحان تو اثر بگذارد).
- 1استفاده از ضمیر فاعلی به جای مفعولی: رایجترین اشتباه زبانآموزان ایرانی است. مثلاً میگویند
*Let he go. دلیل آن این است که در فارسی ضمیر تغییر نمیکند و زبانآموز فکر میکند چون او فاعلِ فعلِ بعدی است، باید از ضمیر فاعلی استفاده کند. در حالی که او مفعولِ فعلِletاست. - 2اضافه کردن
toقبل از فعل: به دلیل ترجمه مستقیم از فارسی (اجازه دادن به انجام دادن)، زبانآموزان به اشتباه میگویند*Let me to go. در انگلیسی بعد ازletهرگزtoنمیآید. - 3فراموش کردن
sسوم شخص: زبانآموزان گاهی فراموش میکنند که در زمان حال ساده، اگر فاعلhe/she/itباشد، بایدletsبگویند. این ناشی از عادت به ساختار فعل در فارسی است که در آن فاعلهای مختلف معمولاً تغییرات مشابهی در فعل ایجاد میکنند.
let با فعلهای دیگر که ساختار مشابه یا متفاوت دارند:Let me go. |Allow me to go. |Make him stop. |allow برخلاف let حتماً به to نیاز دارد. این یکی از نکات ظریف در سطح B1 است.- 1آیا میتوانم بگویم
Let I؟ خیر، هرگز. همیشه بعد ازletباید ضمیر مفعولی (me,him, ...) بیاید. - 2آیا
Let'sهمیشه به معنای پیشنهاد است؟ بله، این مخففLet usاست و برای پیشنهاد دادن به کار میرود. - 3آیا در زمان گذشته هم از
letsاستفاده میکنیم؟ خیر، در زمان گذشته همیشه ازletاستفاده میشود (چون شکل گذشته فعلletهم همانletاست).

'Let's' is a contraction of `Let us`. In modern English, we use the contraction for suggestions and the full form only for very formal permission.
This is a famous biblical quote. While it uses `he` (subject), it is considered archaic. In modern conversation, you should always use `him`.
It can be both! Context matters. If a boss says it, it's a command. If a friend says it about a bad boyfriend, it's a suggestion.
`Let him` is followed by a base verb (`Let him go`). `Allow him` is followed by 'to' (`Allow him to go`).
This is actually grammatically incorrect (it should be 'you and me'), but it is a common mistake even among native speakers.
Yes, if it is the main verb of the clause. For example, `He knows` or `They know`.
Yes! You can say `Let the water boil` or `Let it be`.
It is neutral. It's perfectly fine for both business emails and texting friends.
