Questions & Answers about من از این صابون استفاده نمیکنم چون خودم شامپو دارم.
How does the word khodam work here to mean "myself"?
The word khod means "self". To specify who the self is, you add a possessive ending. Here, we add the first-person singular ending -am ("my") to make khodam ("myself"). In this sentence, it emphasizes that I personally have shampoo.
Why is there an az before in sabun (this soap)?
In Farsi, the compound verb for "to use" is estefadeh kardan. However, this verb requires the preposition az (from) before the object being used. Instead of saying "I use this soap", a Farsi speaker literally says "I do use from this soap".
Where does the negative prefix go in the compound verb estefadeh nemikonam?
When negating a compound verb, the negative prefix ne- or na- attaches to the conjugated "light verb" part, not the noun. Here, the light verb is mikonam (I do), so it becomes nemikonam (I do not do). The noun part, estefadeh (use), stays exactly the same.
Since daram already means "I have", why do we need to add khodam?
You don't strictly need it for the grammar. If you just said chon shampu daram, it perfectly means "because I have shampoo". Adding khodam (myself) adds emphasis, showing a contrast: you are specifying that you personally have shampoo, perhaps in contrast to someone else who needs the soap.
