Root Word

  • Definition - the foundation of the word

  • Gives substance to the meaning.

  • Like a box car in a train, they give the train volume and substance.

  • They come in a variety of different sizes and volumes.

  • There can be more than one in a word.

  • Compound Word


Prefix
Prefix

  • Word that precedes/BEFORE the root, modifying the roots meaning to form a new word.

  • Alone they have some meaning, but they are not complete words without the rest of the word parts.

  • They are like the train’s engine with its whistle.

  • Leads the train and announces the coming train.

  • Without the box cars, together with the engine there is not a complete train.

  • General Rule 1: If the suffix starts with a consonant, connect the rootword and the suffix with the vowel “o”.

  • Example 1:

    Root Word + CV Suffix New word

    Cardi + -o- -logy Cardiology

    “Heart” study of Study of the heart


Word structure combining vowel1

    Root Word + SuffixNew word

    Hepat/o -osis Hepatosis

    liver -disease process - disease process in the liver

Review: Word Structure

  • What is a Root Word?

  • Where can you find a prefix in a word?

  • Where can you find a suffix in a word?

  • What is the most commonly used vowel?

    a. If first letter of suffix = consonant?

    b. If first letter of suffix is = vowel?

    c. If first letter of suffix = last letter of RW?

  • Create a compound word.
