Morphology

lossy = loss (transparent) = loss + y

Productive adjectival formation from the noun 'loss' using the suffix '-y' meaning 'characterized by or causing loss', as in 'lossy compression'.

Etymology

The word lossy comes from the simple word loss, meaning 'the act of losing something', and the ending -y, meaning 'full of' or 'likely to have'. So lossy describes something that lets information or energy be lost, which is why lossy files are smaller but lower in quality.
