Last week I gave a few reasons for avoiding the overuse of famous(ly) in writing. This week’s word(s) to avoid: no doubt, doubt, undoubtedly.
I often read in scholarly writing something like, “This conclusion is no doubt . . . ” or “Scholar X is undoubtedly . . .” etc. To be fair, the sense of the “doubt” terms in those sentences is usually understood a bit looser than the meaning that literary there is no doubt whatsoever.
Even so I prefer the precision of reserving the phrase no doubt for case where there really is no doubt about it.
