In Merriam–Webster, the definition of understand is as follows:
to get the meaning of something / to grasp the meaning of something.
Now my questions are regarding a sentence like:
I don’t understand your instructions.
Is it grammatically correct if I rewrite this sentence with present simple, using get and grasp instead of understand?
I don't get the meaning of your instructions.
I don't grasp the meaning of your instructions.
Do these sentences express the same meaning?
I know understand is a stative verb but are get and grasp stative or dynamic verbs here? Would the sentence mean the same, if I used present continuous:
I don’t understand your instructions?
