The correct answer is True
Step-by-step explanation:
In the English language, the plural form of nouns mainly implies adding an "s" or "es" at the end of the noun as in "girls" that is the plural form of "girl" or in "kisses" that is the plural form of "kiss". Besides, this some nouns experience major changes before adding the "s" or "es" or even other changes as in "babies" that is the plural form of "baby" or in "children" that is the plural of "child". Finally, only in few cases as in "fish" the same word is used for singular and plural. Considering this, it can be concluded it is true that when you make the noun plural, the spelling often changes because it is necessary to add a letter or modify the word in most of the cases which makes the spelling of words (letters of a word) different.
