Questions & Answers about او به اینترنت اعتیاد دارد و یک اپلیکیشن هم پاک نمی‌کند.
How does the structure یک اپلیکیشن هم پاک نمی‌کند translate to 'doesn't delete even one app'?
This showcases the emphatic scalar negation you are learning. By combining یک (one) plus a noun plus هم (also/even) with a negative verb, Farsi creates the meaning 'not even a single [noun]'. Here, یک اپلیکیشن هم paired with the negative verb پاک نمی‌کند emphasizes that he refuses to delete absolutely any apps.
Why do we use the preposition به before اینترنت?
In Farsi, the noun اعتیاد (addiction) requires the preposition به (to) to indicate what the person is addicted to. Just like in English where you have an addiction to the internet, in Farsi you say به اینترنت اعتیاد دارد. This rule also applies to the adjective form معتاد به (addicted to).
I learned that پاک کردن means 'to clean' or 'to erase'. Is it the standard word for 'to delete' digitally?
Yes, it is. While پاک کردن literally means 'to make clean' or 'to erase' in physical contexts, like wiping a table, it has been universally adopted in digital contexts. Whenever you uninstall an app, delete a file, or clear a chat history, you use پاک کردن.
Could I add حتی to this sentence to make the emphasis stronger?
Yes, you can add حتی (even) before the noun phrase to say و حتی یک اپلیکیشن هم پاک نمی‌کند. This adds an extra layer of emphasis. However, as a B2 learner, it is important to master the fact that the یک ... هم structure paired with a negative verb already means 'not even one' entirely on its own.
