"Posingly" is a rarely used adverb that means "in a manner that demonstrates exaggerated self-importance or pretension." Its spelling is quite perplexing, as the "-ing" suffix is typically used to form adjectives, not adverbs. However, the phonetic transcription, /ˈpoʊzɪŋli/, reveals that the word is actually formed from the verb "pose," with the "-ing" suffix indicating a manner or style. Therefore, "posingly" means "in a posing manner," despite its confusing spelling.
