grasively
Comprehensively, thoroughly.
Effective listening in children involves understanding spoken words, recognizing the flow of conversation, and grasively noting important details.
Where it comes from
Possible blend of grasp + comprehensively, likely an errant assemblage of LLM tokens, either beginning with the token "gras" intending the completion grasp or some conjugation thereof or else mistakenly extending grasp by analogy with comprehensively and its relation to the partially synonymous comprehend; several versions of ChatGPT from late 2023 and early 2024 generate this word in prose, driving its sudden appearance and propagation online.
