# 15.12: More Practice with the Third Vowel Rule

Difficulty Level: At Grade Created by: CK-12

## More Practice with the Third Vowel Rule

1. The Third Vowel Rule. The third vowel sound from the end of a word will often be _______ if it is ___________, even if it is the first vowel in a _______ string.

2. In sixteen of the words below the vowel in bold type is covered by the Third Vowel Rule. In the other eight words the vowel in bold type is not covered by the Third Vowel Rule — sometimes because it is not stressed, sometimes because it is not the third vowel sound from the end of the word. In each word put an accent mark over the vowel that has stress on it, and put a ‘3’ under the vowel letter that spells the third vowel sound from the end of the word. If a word does not have three vowels sounds, do not put a number under it. We have given you a start with xerography and committees:

\begin{align*}&\text{xer}\acute{\mathbf{o}}\text{graphy} && \text{r}\mathbf{e}\text{medy} && \text{acc}\mathbf{o}\text{mplish} &&\text{c}\mathbf{a}\text{lculate}\\ & \quad \ 3\\ &\text{c}\mathbf{o}\text{mmíttees} && \mathbf{e}\text{nergy} && \text{pr}\mathbf{e}\text{sident} && \text{sc}\mathbf{i}\text{ssors}\\ &\text{3}\\ &\text{s}\mathbf{o}\text{lvable} && \text{h}\mathbf{e}\text{sitate} && \text{t}\mathbf{e}\text{lephone} &&\text{v}\mathbf{e}\text{nerate}\\ &\text{person}\mathbf{a}\text{lity} && \text{s}\mathbf{y}\text{mphony} && \mathbf{e}\text{xcessive} && \text{s}\mathbf{a}\text{tisfy}\\ &\text{alt}\mathbf{e}\text{rnate} && \mathbf{o}\text{bjective} && \text{d}\mathbf{e}\text{finite} &&\text{t}\mathbf{o}\text{lerate}\\ &\text{amb}\mathbf{a}\text{ssador} && \mathbf{e}\text{lephant} && \text{aff}\mathbf{e}\text{ction} && \text{m}\mathbf{i}\text{grant}\end{align*}

3. Sort the words into the two groups described below. Remember that for one of these vowels to be covered by the Third Vowel Rule, it must have an accent mark over it and a ‘3’ under it. In the Reason column show why the vowels in bold type in the eight words are not covered by the rule: Put “No stress” if they are not stressed or “Not #3” if they are not spelling the third vowel sound from the end of the word:

4. In the sixteen words in which the vowel in bold type is covered by the Third Vowel Rule, eleven of the bold vowels are the first vowel in a VCV string; five are in a VCC string. Sort the sixteen words into these two groups:

5. Are the vowels in the VCV strings in the eleven words long or short? ___________
