There are arguably better adverbs than the ones that have been overused or misused. I’m usually uncertain what is really meant when the word arguably is used. I hear it given more power than it has. Hypothetical example: Today was arguably the worst weather we’ve had this month. It was obviously the worst weather this month and only a fool would argue the point, but the adverb is thrown in with the intention that it bolsters the position rather acting as a disclaimer. Arguably means it is something that can be argued, disputed, questioned. It’s indisputable that arguably has been distorted.
