Questions & Answers about شما لامپ را روی سقف نصب نکردهاید.
How do we form the negative present perfect in نکردهاید?
This is the negative present perfect of the helper verb کردن (to do). It is built by adding the negative prefix na- to the past participle کرده (done), followed by the short 'to be' ending for 'you' (formal/plural), which is -اید (-id). Altogether: na- + karde + -id makes nakarde-id.
What is the full verb for 'to install' in this sentence?
The full verb is the compound verb نصب کردن (to install). In Farsi, many verbs are made of a noun (نصب, meaning 'installation') plus a helper verb like کردن (to do). When conjugating into the negative present perfect, only the helper verb changes, becoming نکردهاید.
Why is the word را placed right after لامپ?
The word را is the definite direct object marker. Because the sentence refers to a specific lamp ('the lamp' that you did not install, rather than just 'a lamp' in general), we must use را immediately after the noun it marks.
How do we connect the word for 'on' (روی) to 'ceiling' (سقف)?
Prepositions of location like روی (on or on top of) require the Ezafe to connect to the noun that follows them. This means you must add an invisible 'e' sound between the two words, so they are pronounced 'rooy-e saghf'.
