Infinitive of a verb

Infinitive is the basic form of a verb. For example: to do, to go.

Infinitive ending

Today, infinitives end in either «-dan» or «-tan». They all originally ended in «-tan» but it changed to «-dan» after vowels and the consonants «n, r»:

  • dâshtan (to have)
  • bastan (to close)
  • raftan (to go)
  • goftan (to say)
after vowels
  • âmadan (to come)
  • dâdan (to give)
  • didan (to see)
  • shodan (to become)
  • budan (to be)
after «n»
  • khwândan (to read)
  • kandan (to dig)
after «r»
  • kardan (to do)
  • khordan (to eat)

Apocopated infinitive

Infinitives have a short form, technically referred to as «apocopated infinitive», which in certain cases, is used in place of full form. An infinitive is apocopated by removing «-an» from its end.
