pre·VENT·ful·ly
Out of a temperament organised around what one is avoiding — as distinct from preventively, which describes a purpose rather than a disposition.
He lived preventfully, and had nothing to show for it but the absence of disasters.
Etymologyprevent + -ful + -ly. -ful takes verbs where it means 'inclined to' — forgetful, watchful, resentful, regretful.
NoteProposed as preventifully; the -i- was spurious. -ifully is a -y noun + -ful + -ly, and that i is a mutated y (beauty, duty, mercy). Your word minus one letter.
