08824 Hithpolel

This Hebrew form is equivalent in use to the Hithpael, and is
causative/reflexive in meaning.  The separate term occurs because
certain verb forms reduplicate their final consonant and change into
a quadriliteral (4-letter) root rather than the normal triliteral
(3-letter) root form.  This form additionally lengthens the initial
vowel in the first consonant.
