1. Mind Moo-ver • Objective: • SWBAT – recognize common root words, prefixes, suffixes. • SWBAT – understand the function of root words, prefixes, suffixes • QOD: • What are some terms you can think of associated with the veterinary field? How have you heard animal scientists describe animals.. What terms do they use? Give examples.

5. The Building Blocks Suffix Root Prefix Combining Form

6. Word Structure • Root Word • Prefix • Suffix • Combining Vowel • Compound Word The key to learning terminology is to break down each word into parts and learn the most common roots, prefixes, suffixes, and combing forms.

7. 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. Suffix Root Prefix Combining Form

On your notes sheet, there are boxes with each of the following terms. It is you mission to write down what the term is referring to and create an icon that is representative of the term.

9. Root Word Examples - 1 Cardi/o – Heart Cephalo/o – Head Dent/o – Tooth, Teeth Mamm/a, Mamm/o – Mammary Gland Nas/o – Nose, Nasal

15. Prefix Word Examples On the upper right hand corner of the your PREFIX sheet there is box. Please create an ICON that represents Prefixes. On your notes sheet, there are boxes with each of the following terms. It is you mission to write down what the term is referring to and create an icon that is representative of the term.

16. Prefix Examples - 1 A-, an- Not, Without Anti- Opposing, Against Brady- Slow De- Away from Dys- Difficult

17. Prefix Examples - 2 Hyper- High, Above, Beyond Hypo- Low, Below, Behind Mal- Bad, Poor Poly- Many

28. Suffix Examples - 4 -osis – Abnormal condition -oxia- Oxygen -phagia– Eating, Swallowing -spasm– Involuntary Contraction -toxin– Poison

29. Word Structure: Suffix • Example: Root Word + SuffixNew word Tonsil + -itisTonsilitis -itis = inflammation of Inflammation of the tonsils

30. Exercise on Suffixes • Hyper- adrenocortic -________ (state…) (Adrenal cortex) • Acar/i -________ (tick/mite infestation) • Gastr/i-________(inflammation of the stomach lining)

32. Word Structure: Combining Vowel • Vowel commonly used: “o” • 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

37. 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.

38. Create a Word Activity • For each group there are three “dice.” • Prefix • Rootword • Suffix • Each person is to take three rolls of each dice to create three words. • Write out the correct notation, including combining vowels/words and its meaning.
