Conversation

Have you heard about lossy compression for images?

Yeah, it reduces the file size but can affect the quality, right?

Exactly! Some people don’t mind the quality drop for smaller files.

True, but I prefer keeping my photos in higher quality when I can.

Root Explanation

Lossy → The word is derived from 'loss' (from Old English 'los', meaning the act of losing or being deprived of something) and the suffix '-y' (meaning characterized by or having the quality of). Thus, 'lossy' describes something characterized by loss, particularly in contexts like data compression where some information is lost.

Memory Tip

Think of 'loss' as being deprived of something, and remember that 'lossy' means having the quality of losing information.
