. ▁In ▁the ▁case ▁of ▁trans itive ▁ver bs , ▁another ▁argument ▁is ▁added ▁to ▁the ▁val ency ▁of ▁the ▁verb , ▁while ▁in trans it ives ▁maintain ▁their ▁initial ▁val ency . ▁This ▁suffix ▁is ▁used ▁relatively ▁rarely ▁with ▁in trans itive ▁ver bs , ▁and ▁of ▁all ▁the ▁examples ▁given ▁below ▁begin ▁with ▁/ e /, ▁so ▁it ▁is ▁the or ised ▁that ▁these ▁ver bs ▁take ▁this ▁suffix ▁because ▁they ▁are ▁derived ▁from ▁trans it ives , ▁however ▁this ▁theory ▁has ▁not ▁been ▁proven . ▁{ | ▁class =" wik itable " ▁!
