muSIghbe' nepbogh 'ej tojmeH mu'meylIj
your lying and deceiving words don't deceive me

Would that be correct? Could we create a noun which is both {-meH}'ed and {-bogh}'ed?

You can make a noun that participates in both a relative cause and a purpose clause, but I don't believe you can 'ej them.

You can't say, for instance, nepbogh 'ej tojmeH which lies and for deceiving.

You CAN say nepbogh tojmeH mu'meylIj your words for deceiving which lie.

But why would you want to say it this way? Why not say nepbogh mu'meylIj 'ej tojbogh your words which lie and which deceive?
