No.  I imagine it was dropped just to save a little typing.  However it’s spelled with a {y}.  Here’s how I have it in my notes:

yItlh                       be strict, severe, firm, stern, authoritarian (v) TLP

yItlhHa'                 be lenient, indulgent (v) TLP

Appropriately {ghItlhHa’} would mean “mis-write”, e.g. to make a typo!

From: mayqel qunen'oS

Usually, be-verbs are given as "be hot", "be tall", "be silent" etc.

Would there be a reason, that the ghItlhHa' was given as "lenient, indulgent" instead of "be lenient, indulgent" ?

Does the missing "be" change anything ?
