Free of charge; provided without cost or obligation; having no electrical charge.
From 'charge' plus '-less' suffix meaning without. This formation directly opposes 'chargeable'—the two words use opposite suffixes to create opposite meanings, a elegant pattern in English.
The word 'chargeless' is rare because 'free' and 'free of charge' are much simpler. This shows that even when English has grammatically perfect words, everyday speech gravitates toward the shortest, simplest option.
