Grammar. Parts of Speech for 2nd Grade. Irregular Plural Nouns

Dec. 30, 2021

At home, you might have rules for your children that can be set aside in special circumstances. For instance, suppose your kids are only allowed to play learning games for an hour; but whenever they perform well in their rehearsals, you reward them with an extra hour of playing. In grammar, there are also exceptions to the rules. Your kids are already acquainted with pluralizing nouns. However, there are some plural nouns that do not abide by the rules on pluralizing nouns by adding -s or -es. They are referred to as irregular plural nouns. They are nouns that change or retain their spellings when they are pluralized. Examples are:

child – children,

man – men,

woman – women,

loaf – loaves,

tooth – teeth,

oasis – oases,

axis – axes,

fish – fish,

mouse – mice,

ox – oxen.

Let your kids observe the examples. Ask them if they see patterns in pluralizing irregular nouns. If they happen to see any, process their observations. If they cannot discern, tell them that irregular plural nouns do not follow a uniform rule, but there are some recognizable rules for them:

  • Some nouns change their vowels when pluralized such as in the examples: men, women, teeth, oasis, and axes.
  • Other nouns retain their spellings despite being converted to their plural forms like in the case of the word fish.
  • Most nouns ending with -f are pluralized by changing f with v and adding -es afterwards, as exemplified by loaf when changed to loaves.
  • Some nouns are added with letters at the end (other than s and es) to form their plural equivalents as in from the word child to children and from ox to oxen.
  • Lastly, other nouns change their spellings like what happens to mouse shifting to the plural counterpart, mice.

However, it is noteworthy to mention that since there are a lot of irregular plural nouns, your kids are advised to memorize irregular plural nouns that they will encounter, so they can reserve them for future use. If unsure, tell them they are allowed to consult a dictionary once in a while if needed. To build a more profound understanding of irregular plural nouns, here are the gripping learning worksheets for your children:
