Characterized by gasping; inclined to gasp or breathe heavily; short of breath.
From gasp plus informal adjective suffix -y (Old English -ig). Created as a colloquial or literary descriptor rather than formal scientific term.
Gaspy is the kind of informal adjective speakers create on-the-fly—you wouldn't find it in dictionaries often, but a 19th-century novelist might write it to avoid repeating 'out of breath' too many times.
