In the text of the earlier grades, emphasis has been frequently directed
toward the changes in words in forming plurals and adding suffixes and
prefixes. Very little has been said when the only change has been the
adding of “_s_.” This regular form causes no great trouble.
During the fifth year a few simple rules are presented. These have been
frequently illustrated in earlier grades. The rules presented are those
for which there is frequent use.
On pages 14, 17, and 19 the rule for writing derivatives of words ending
in _y_ preceded by a consonant is given with many illustrations.
Throughout the year’s work, however, these words are occurring. Such
words will be found in Lessons 20, 32, 34, 37, 39, 40, 41, 42, 50, 59,
91, 114, 115, 156. On page 28 the rule for writing the plurals of nouns
ending in _f_ or _fe_ is given with illustrations. After these rules are
taught the teacher should take every advantage offered for fixing the
rules.
