In a manner that lacks design, intention, or purpose; by chance or accident without any deliberate planning.
From 'designless' (adjective meaning without plan or purpose) + '-ly' (adverb-forming suffix). This adverbial form lets speakers describe actions that unfold without any guiding intention.
Imagine describing how your favorite song was discovered—maybe you accidentally clicked it, it came on shuffle, and now it's your anthem. That's designlessly: none of it was planned, yet something meaningful came from total chaos.
