More About Changing <y> to <i> and Some Review of Rules and Sounds

1. Earlier you saw that sometimes when we add a suffix to a stem that ends in a <y> that has a consonant right in front of it, we change the <y> to <i>. For example:

cry+ed=cry+i+edeasy+est=easy+i+est=cried=easiest

But notice what would happen if we changed the <y> to <i> when the suffix starts with an <i>:

accompany+ing=accompany+i+ing=accompaniing

We would get <ii>. In English we avoid <ii>. So when we add a suffix that starts with an <i> to a stem that ends in <y>, we use simple addition:

accompany+ingtoy+ing=accompanying=toying

2. When you add a suffix that starts with an <i> to a stem that ends in a <y>, you use ________________________; when the suffix starts with any other vowel, and the <y> has a consonant right in front of it, you change the _____ to _____.

3. Combine the following prefixes, stems, and suffixes. Show any cases of twinning,silent final <e> deletion, changes of <y> to <i>, and assimilation. Watch for cases where the <y> does not change to <i>:

Elements = Word
ad + p + ply + ing = applying
bathe + er + s =
un + ad + feet + ion + ate =
choose + y + est =
up + set + ing =
glimpse + ed =
un + re + serve + ed + ly =
ad + venture + ous =
re + ad + sure + ed =
re + gret + ing =
dis + solve + ing =
gauze + y =
early + est =
achieve + er + s =
soothe + ing + ly =
ad + company + ing =
re + ad + ply + ed =

4. You can hear the sound [t] at the beginning and end of the word toot.

You can hear the sound [d] at the beginning and end of the word dude.

5. Underline the letters that spell [t] and [d] in the following words:

candidateaddressincludeadventurestubbornbitingbuildingelectricbenefithospitalsucceedmotorstrugglevegetableghetto

6. Sort the fifteen words into these two groups. Some words will go into both groups:

7. Two ways to spell [t] are _____ and _____.

Two ways to spell [d] are _____ and _____.

Word Venn. Into circle A put only words in which a <y> has been changed to an <i>. Into circle B put only words that contain the sound [t]. Into circle C put only words that contain the sound [d]:
