A person who does not like you. Someone who wants to hurt you. That is an enemy.
Today we learn four words. “Enemy,” “enmity,” “enemies,” and “unfriendly.”
Each word shares the idea of opposition or dislike. Each does a different job.
Parents and children can learn these words together. They help with social skills.
What Does “Same Word, Different Forms” Mean?
One idea takes different shapes. The idea here is hostility or dislike.
“Enemy” is a noun (singular). “The hero fought his enemy.” Foe.
“Enmity” is a noun. “There was enmity between the two groups.” Hostility.
“Enemies” is a noun (plural). “They became enemies after the argument.” Multiple foes.
“Unfriendly” is an adjective. “An unfriendly person does not smile.” Describes.
Same root. Different endings. Different jobs. The hostility stays.
Personal Pronouns Change Their Form
Pronouns change for grammar. “I” becomes “me.” “We” becomes “us.”
Our words change for number and description. “The enemy attacked.” One foe.
“Enmity grew.” Hostility. “They are enemies.” Many foes.
“She was unfriendly.” Describes.
Pronouns help us speak faster. Word families help us talk about conflicts.
When children know these four words, they describe social problems.
From Verb to Noun to Adjective to Adverb – One Family, Many Words
“Enemy” is a noun (singular). “The spy avoided his enemy.” Foe.
“Enmity” is a noun. “The enmity between the two cats was obvious.” Hostility.
“Enemies” is a noun (plural). “They became enemies after the disagreement.” Foes.
“Unfriendly” is an adjective. “An unfriendly tone hurts feelings.” Describes.
We have no verb or adverb in this family.
Four members. Very useful for stories and real life.
One Root, Many Roles – How Words Grow from Actions to Qualities
The root “enemy” comes from Latin “inimicus.” “In-” means not. “Amicus” means friend. Not a friend.
From that root, we have “enemy” (singular) and “enemies” (plural).
“Enmity” adds “-ity” to make a noun from the Latin root “inimicitas.” It means the state of being an enemy.
“Unfriendly” adds “un-” to “friendly.” “Friendly” comes from “friend.” Unfriendly means not friendly.
Help your child see this pattern. Enemy is a single foe. Enemies are multiple foes. Enmity is the hostile feeling. Unfriendly describes a cold behavior.
Same Meaning, Different Jobs – Is It a Verb or a Noun?
Look at “enemy.” Always a noun. “The hero defeated his enemy.”
“Enmity” is always a noun. “There is deep enmity between the rivals.”
“Enemies” is always a noun (plural). “They became enemies.”
“Unfriendly” is always an adjective. “The salesperson was unfriendly.”
No word plays two jobs. Each has one clear role.
Teach children that “enemies” is simply the plural of “enemy.”
Adjectives and Adverbs – When Do We Add -ly?
We add “-ly” to “unfriendly” to make “unfriendlily.” Very rare. “He spoke unfriendlily.” Skip it.
We do not add “-ly” to “enemy,” “enmity,” or “enemies.”
For children, skip adverbs. Focus on the nouns and the adjective.
Watch Out for Tricky Spelling Changes (Double Letters, y to i, and More)
Spelling has a plural rule. “Enemy” → change “y” to “i” and add “es.” Enemies.
“Enmity” stays the same. “Unfriendly” keeps the “y.” Unfriendly is one word.
No double letters.
Practice with your child. Write “enemy.” Change “y” to “i,” add “es.” You get “enemies.” Write “enmity” separately. Write “un” + “friendly.” You get “unfriendly.”
