Causative Verbs

Consider the different between "to laugh" and "to make someone laugh". To get from the former to the latter, instead of using an extra verb like "make", Persian addes a suffix to the main verb. This new verb is called a causative verb.
To make a causative present stem, add “ان” to the end of the regular present stem, e.g., “خواب” for "to sleep" becomes “خوابان”. To make its past stem, add a to what you made, i.e.., “خواباند”
This gives us a whole new set of verbs that are easy to memorize since they are made using the verbs we are already familiar with. Below are some examples.
Causative Verb (transitive) Intransitive Verb
