Creating adjectives using the suffixes -ful and -less

The suffixes -less and -ful create adjectives. The suffix -ful means ‘full of’ or ‘having qualities of’ and the suffix -less means ‘without’ or ‘lacking’. The suffixes start with a consonant. This means the root word usually doesn’t change when the suffix is added. If the root word ends in a consonant +y, then the ‘y’ is replaced by ‘i’ before the suffix. How to spell the curriculum words: awkward, bruise, regular and therefore.
