Unplannedly

Unplannedly: adverb. The word unplannedly is the adverb derived from the more commonly used adjective "unplanned." It can be used in sentences such as "the authors of this blog unplannedly came up with this word whilst writing tomorrow's post." The word unplannedly is synonymous with the words "inadvertently," "unintentionally," or "unwittingly," but covers a somewhat larger scope in meaning, as exemplified by the previous sentence which would convey a slightly different message if the word unplannedly was replaced by any of these.
