In the word "inconceivable," which of the following is the root word?

  1. In

  2. Conceive

  3. Ceivable

  4. Cable

The correct answer is: Conceive

In the word "inconceivable," the root word is "conceive." This root originates from the Latin word "concipere," which means to take in, form, or imagine. In this context, the prefix "in-" is used to indicate negation, meaning "not," which transforms "conceive" into "inconceivable," or "not able to be conceived or imagined." Understanding the root word is essential because it reveals the core meaning of the term. By identifying "conceive" as the root, you can better grasp how the additions of prefixes and suffixes modify the meaning of words in the English language. Recognizing root words helps in expanding vocabulary and comprehending similar words that share the same base.
