Questions & Answers about شما باید برای این کلاس رسمی ثبتنام کنید.
Why does the sentence use کنید instead of the normal present tense میکنید?
The word باید (must) is a modal verb that requires the main verb to be in the present subjunctive form. This is the exact same rule you are learning with قرار است (it is planned). Because of باید, the compound verb ثبتنام کردن (to register) drops its continuous می prefix, becoming ثبتنام کنید.
I learned to use که (that) with expressions like قرار است. Should there be a که after باید here?
No, باید does not require که (ke). While impersonal phrases like قرار است usually need که to connect to the rest of the sentence (literally 'it is planned that...'), باید simply means 'must' and connects directly to the rest of the sentence without it.
Why isn't there a بـ (be-) prefix on the subjunctive verb کنید?
For compound verbs formed with کردن (to do), such as ثبتنام کردن (to register), native speakers almost always drop the بـ (be-) prefix in the subjunctive. While ثبتنام بکنید is technically correct, ثبتنام کنید is much more natural and common.
How do the words in این کلاس رسمی link together grammatically?
Demonstrative words like این (this) always come before the noun and do not take an ezâfe (the linking 'e' sound). So, it is just این کلاس (in kelâs). However, رسمی (formal) is an adjective describing the class, so we must link the noun and adjective with an ezâfe, giving us این کلاسِ رسمی (in kelâs-e rasmi).
