Without heaviness; light or lacking weight; not burdened or weighed down (archaic or poetic).
From 'heavy' (where the root becomes 'heav-' when adding suffixes) + '-less' suffix meaning 'without.' This formation is theoretically valid in English morphology but is archaic and rarely seen in modern usage.
This word almost never appears in surviving texts, yet it follows English rules perfectly—'heavy' + '-less' = 'heaveless.' It's a ghost word: possible but never really lived! This shows that not every grammatically correct word becomes part of the language.
