Unless I'm missing something, I am not seeing the imperative in the morphology chart for לקח:
Maybe there is a reason for this, but I would have thought it was an error. Can I report this somewhere?
See this thread I started over 3 years ago! There were some improvements, but I'm not aware there the morph charts were ever totally fixed. Please do take up the baton and remind FL about these. After all, we did pay for them!
I tried a few other Hebrew verbs (נתן, ראה) and they don't have the imperative either. Maybe all morphology charts for Hebrew verbs are missing the imperative.
