jack.chaney56 mentioned that his favourite word was "Just" as in, "it just works" which often hides a massive amount of work done by others to make it happen for you.
My favourite is "Simply" which comes up in our requirements statements. e.g. "It simply needs to guide the rocket and land on the asteroid". We find it used most when the person writing the request has no idea at all about what needs to be done.
