What Does “Same Word, Different Forms” Mean? One root word can grow into different shapes. “Comparison, comparative, comparable” share one meaning. That meaning is “looking at two or more things together.” Each form has a different job in a sentence. Some words name the act of comparing. Some words describe the type of grammar. Some words say that things are similar enough to compare. Learning these three forms builds clear thinking.
Personal Pronouns Change Their Form This rule applies to pronouns like “he, him, his.” But word families work the same way for other words. “Comparison” is a noun. “Comparative” is an adjective. “Comparable” is also an adjective. Each form answers a different question. What thing or act? Comparison. What kind of grammar or degree? Comparative. What kind of similarity? Comparable.
From Verb to Noun to Adjective to Adverb – One Family, Many Words This family starts with the verb “compare.” From “compare,” we make the noun “comparison.” “Comparison” names the act of looking at similarities and differences. Example: “A comparison of dogs and cats shows many differences.” From “compare,” we also make the adjective “comparative.” “Comparative” describes the form of an adjective that shows more. Example: “Bigger is the comparative form of big.” From “compare,” we make another adjective “comparable.” “Comparable” means similar enough to compare. Example: “These two phones are comparable in price.”
One Root, Many Roles – How Words Grow from Actions to Qualities Think of two apples on a table. You look at both. You find how they are the same. You also find how they are different. That whole activity is a “comparison.” When you say one apple is “redder” than the other, “redder” is the “comparative” form. If the two apples are close in size, you say they are “comparable.” The root meaning stays “looking together.” The role changes with each sentence.
Same Meaning, Different Jobs – Is It a Verb or a Noun? “Comparison” is always a noun. It names an act or a result. Example: “Make a comparison between summer and winter.” “Comparative” is always an adjective. It describes a type of word or a degree. Example: “Better is the comparative form of good.” “Comparable” is always an adjective. It describes two things that can reasonably be compared. Example: “The two houses are comparable in size.” No verb form appears in this set. The verb is “compare.” Same family. Different jobs.
Adjectives and Adverbs – When Do We Add -ly? “Comparative” and “comparable” are both adjectives. To make adverbs, you could add -ly. “Comparatively” and “comparably” are the adverb forms. Example: “The second car is comparatively cheaper.” But this lesson focuses on the three key forms. The pattern is clear. Adjectives describe nouns. Adverbs describe verbs, adjectives, or sentences. Knowing the root helps you guess the other forms.
Watch Out for Tricky Spelling Changes (Double Letters, y to i, and More) “Comparison” has no double letters. But watch the middle: comparison, not comparizon. “Comparative” has no double letters. But note the “a” after “r”: comparative. “Comparable” has no double letters. But note the stress changes. We say comparable (stress on first syllable). We say comparative (stress on second syllable). A common mistake is writing “comparitive” instead of “comparative.” Remember the “a” after “r.” Another mistake is writing “comparable” with an “e” in the middle. It is comparable, not comperable.

Tips for Parents – Help Your Child Learn Word Families in a Fun Way You can teach “comparison, comparative, comparable” through daily life. Use food, toys, and simple conversations.
At snack time, put two fruits on a plate. Say “Let’s make a comparison. Which is bigger?” Let your child describe both.
