Suffixes often change a word's part of speech — turning 'care' into 'careful' or 'careless' — so understanding them helps you use words correctly and expand your vocabulary quickly.
Recognising suffixes also boosts reading and spelling, because you can decode unfamiliar words by their parts rather than guessing.
