The word "anacamptically" is spelled quite uniquely. It starts with the prefix "ana-" meaning upward or back, then "campt-" meaning bent, and ends with "-ically" which means with or by. The word is pronounced /ˌænəkæmˈtɪkəli/ in IPA phonetic transcription. It is an adverb used to describe something done in a way that gradually intensifies, like the volume of music increasing. While it may be a difficult word to spell, it is an interesting term to use in writing.
