I read this in a contract " this agreement shall be construed, governed, interpreted and applied"

Lawyers draft docs like this to cover all bases, and to give judges options to agree with your side, and to prevent opposing counsel from claiming one narrow definition. For the purposes of informal interpretation, you can omit a redundancy. For more exacting stuff, do not omit anything, but repeat the only interpretation you have and place [sic] after the redundant word if there is nothing else available.
