How the suffix -less changes meaning

Adding -less to a noun creates an adjective meaning without that noun, so care plus less becomes careless, meaning without care. This pattern is one of the most predictable in English, which makes it a useful entry point for teaching suffixes. Once learners spot the pattern, they can often guess the meaning of an unfamiliar -less word just from its base noun.
