More About Suffixes and <y> to <i> Changes

1. Here is another chance for you to try out your new rule for spelling plural nouns. Add either s or -es to each singular noun. Be sure to show any changes:

Singular Noun + Suffix = Plural Noun
ability+ i + es = abilities
dance + s = dances
six + es = sixes
yesterday + s = yesterdays
memory+ i + es = memories
demand + s = demands
match + es = matches
Wednesday + s = Wednesdays
family + i + es = families
design + s = designs
crush + es = crushes
library+ i + es = libraries
beauty+ i + es = beauties
pattern + s = patterns
success + es = successes
attorney + s = attorneys

2. You've seen that <y> changes to <i> when you add the suffix -es to singular nouns that end in a <y> with a consonant right in front of it. A <y> with a consonant in front of it changes to <i> also when you add the suffixes -ed or -er or -est.

3. Watch for all kinds of changes when you combine the following words and suffixes to make new words:

Word' + Suffix = New Word
supply + i + er = supplier
bottle + ed = bottled
arrive + ing = arriving
stop + p + er = stopper
white + est = whitest
like + ed = liked
try + i + ed = tried
use + er = user
bat + t + ing = batting
surprise + ed = surprised

4. Here are some to do the other way round:

Word = Shorter Word + Suffix
dancer = dance + er
supplied = supply + i + ed
waltzing = waltz + ing
arrived = arrive + ed
designer = design + ed
silier = silly + i + er
phoning = phone + ing
writer = write + er
guessing = guess + ing
pitcher = pitch + er
