While I think this advise of yours should be clear to any user of a thesaurus or this site, I figured I'd share my default answer to a replacement for "very hard".
"very hard" -> "difficult"
Which is interesting because that's also an opinionated synonym for "hard", which without context has many definitions and interpretations. I'm also not even sure I think of "difficult" as being more hard than hard. I digress. Have a good evening.
