Questions & Answers about اعتیاد به گوشی یک مزاحمت بزرگ است.
Since this lesson is about using 'yek' for 'not even one', why doesn't it mean that here?
For یک to mean 'not even one', it must be paired with هم and a negative verb. Because this sentence uses a positive verb (است) and lacks هم, the word یک is simply acting as the standard article 'a' (a big disturbance). If you wanted to apply the lesson's grammar to say 'It is not even one big disturbance', you would say یک مزاحمت بزرگ هم نیست.
Does the noun اعتیاد (addiction) always take the preposition به (to)?
Yes, just like in English, the noun اعتیاد (addiction) and its related adjective معتاد (addicted) are followed by the preposition به (to). So, اعتیاد به گوشی translates perfectly to 'addiction to the phone'.
Why use گوشی (guši) instead of تلفن (telefon) for 'phone' here?
While تلفن is the general word for telephone, گوشی (which historically meant 'earpiece' or 'receiver') is the standard, everyday word Iranians use for a mobile phone or smartphone. At a B2 level, using گوشی will make your spoken Farsi sound much more natural.
Where exactly does the spoken 'ezafe' link go in the phrase یک مزاحمت بزرگ?
The ezafe connects a noun to its adjective, so it attaches to the end of the noun: مزاحمتِ بزرگ (mozāhemat-e bozorg). The number/article یک comes before the noun and never takes an ezafe itself.
