Questions & Answers about Нужно подшить брюки.
Нужно means it is necessary, one needs to, or it’s needed.
In Нужно подшить брюки, the idea is:
It is necessary to hem the trousers
or more naturally in English, The trousers need to be hemmed.
This is a very common Russian impersonal construction:
- Нужно + infinitive
- Надо + infinitive works similarly
For example:
- Нужно идти. = We/I/one need(s) to go.
- Нужно позвонить. = It’s necessary to call.
Because this is an impersonal sentence.
Russian often leaves out the person responsible when the main idea is simply that something needs to be done. English often does something similar with phrases like:
- It’s necessary to...
- You need to...
- This needs to be...
So Нужно подшить брюки does not say exactly who must do it. Depending on context, it could mean:
- I need to hem the trousers
- We need to hem the trousers
- The trousers need hemming
- Someone needs to hem the trousers
Russian is comfortable leaving that unspecified.
