Questions & Answers about دادوستد در این بازار سخت است.
How does the word dâd-o-setad (trade) fit the pattern of combining two past stems?
It is built directly from the past stem dâd (from dâdan, to give), the conjunction o (and), and the past stem setad (from setadan, to take/receive). Combining two opposite or related past stems like this is a common way to create abstract nouns of action. Literally meaning "gave and took", it functions here as a single noun meaning "trade" or "commerce".
Is setadan a normal verb I should be using for "to take"?
No, in everyday modern Farsi you will almost always use gereftan for "to take". setadan is an older, more literary verb. You will mostly see it surviving in fixed compound nouns like dâd-o-setad rather than being conjugated as a regular verb in conversation.
Could I say dâd-o-gereft instead, since gereftan is the modern word for "to take"?
No, these past-stem compound nouns are fixed phrases that have been passed down through the language. Even if the verbs inside them feel old-fashioned, you cannot swap them out for modern equivalents. You must memorize dâd-o-setad as a set vocabulary word.
Why is دادوستد written tightly together without spaces?
When the conjunction o (and) is used to create a single compound noun from two stems, the spaces are often dropped to show it is one unified word. Even though the letters د and و don't physically attach to the letters after them, keeping them grouped closely together visually tells the reader this is the single concept "trade".
