4 Did you notice the suffixes -ful, -less in words that you have come across fromUnits 1–6, such as harmful, dreadful, joyless, restless? Both suffixes can beadded to nouns or verbs to form adjectives. When added to nouns, -ful canmean “full of” or “having the quality of”, such as careful; while -less can mean“without” or “not having the quality of”, such as careless. In this case, -ful canbe understood as the opposite of -less. But when added to verbs, -ful can mean“apt to, able to; accustomed to”, such as forgetful, while -less can mean “cannotbe -ed”, such as countless.
