Verbs (Simple Past Tense)

[Roman Abdul Satar]

In English there are verbs that irregular (to go) and regular (to clean), however in Persian it's not the verbs that define the regularity or irregularity of the verbs. In Persian the tense is regular or irregular. For example, the verbs in simple past tense are regular while in present simple tense are irregular. All tenses except present can be regular.
In Persian there is not a well-defined rule for grammar.

In simple past tense almost all verbs are regular. For example the word to go رفتن (raftan) and to go the simple past tense we just need to drop the letter n, we will have رفت (raft). So in all verbs ending is N, by just deleting that letter we get simple past tense verb.
