The suffix “-sion” typically transforms verbs into nouns, signifying the act, state, or result of the verb’s action. For example, “extend” becomes “extension,” indicating the act of extending or the state of being extended. This morphological process is derived from Latin and is prevalent in English vocabulary.
Understanding this derivational suffix is crucial for vocabulary building and comprehension. Recognizing the root verb often unlocks the meaning of the derived noun. This knowledge enhances reading comprehension and facilitates nuanced expression in writing. Historically, the adoption of “-sion” words reflects the influence of Latin on the development of the English language.
