Use suffixes to craft your lexicon and let your speech sparkle!

Don’t just sit idly by — give your speech some fire by mastering suffixes! Suffixes are an easy way to modify, or change the meaning of words without changing the base word — imagine the possibilities! Mastering suffixes is simple when you understand the fundamentals.

A suffix is an affix added to the end of a word, often transforming its meaning. Familiarize yourself with the common suffixes used in English and you’ll be able to define any concept simply.

Use -able/-ible as an adjective to describe something that can be done or experienced. For example, “comfort” + “able” = “comfortable”; “respect” + “ible” = “respectible”.

The suffix -ly will add the quality of something. “Quick” + “ly” = “Quickly”; “Grace” + “ly” = “Gracefully”.

The suffix -ness will turn the adjective form into a noun, with a meaning of the quality in question. “Gentle” + “ness” = “Gentleness”; “Soft” + “ness” = “Softness”.

Suffixes can also change a verb into a noun, like -er/-or. “Decide” + “er” = “Decider”; “Calculate” + “or” = “Calculator”.

The suffix -ment will typically convert a verb into a noun to express an action or result. “Employ” + “ment” = “Employment”; “Invest” + “ment” = “Investment”.
