Your friend asks why the sky is blue. You tell them about sunlight and air.
You explain it. Today we learn four words.
“Explain,” “explanation,” “explanatory,” and “explained.”
Each word shares the idea of making something clear. Each does a different job.
Parents and children can learn these words together. They help with understanding.
What Does “Same Word, Different Forms” Mean?
One action takes different shapes. The action here is describing so someone understands.
“Explain” is a verb. “Please explain the rules.” Action.
“Explanation” is a noun. “Your explanation was helpful.” Description.
“Explanatory” is an adjective. “An explanatory note clarifies things.” Describes.
“Explained” is a past tense verb or adjective. “She explained the math problem.” Past action. “The explained concept.” Describes.
Same root. Different endings. Different jobs. The clarity stays.
Personal Pronouns Change Their Form
Pronouns change for grammar. “I” becomes “me.” “We” becomes “us.”
Our words change for role and time. “I explain the map.” Present.
“Your explanation is clear.” Noun. “That diagram is explanatory.” Describes.
“He explained the answer.” Past.
Pronouns help us speak faster. Word families help us talk about teaching.
When children know these four words, they ask for clarity.
From Verb to Noun to Adjective to Adverb – One Family, Many Words
“Explain” is a verb. “Explain your answer.” Action.
“Explanation” is a noun. “His explanation made sense.” Description.
“Explanatory” is an adjective. “Explanatory notes help readers.” Describes.
“Explained” is a past verb. “The teacher explained the lesson.” Past action.
“Explained” is also an adjective. “The explained rule was easy to follow.” Described.
We have an adverb “explanatorily” from “explanatory.” Rare.
Five members. Essential for school and homework.
One Root, Many Roles – How Words Grow from Actions to Qualities
The root “explain” comes from Latin “explanare,” meaning to make plain or flatten. “Ex-” out + “planus” flat.
To make flat and clear.
From that root, we add “-ation” to make a noun. “Explanation” means the act of explaining.
We add “-atory” to make an adjective. “Explanatory” means serving to explain.
We add “-ed” for past tense or to make an adjective meaning “clarified.”
Help your child see this pattern. Explain is the action. Explanation is the statement. Explanatory describes the helper. Explained means already clear.
Same Meaning, Different Jobs – Is It a Verb or a Noun?
Look at “explain.” Always a verb. “Explain the process.” Action.
“Explanation” is always a noun. “The explanation was too long.”
“Explanatory” is always an adjective. “An explanatory video helps.”
“Explained” can be a past verb or adjective. “He explained the problem.” Past verb. “The explained point.” Adjective.
No word plays two jobs except “explained” (past verb and adjective).
Teach children that “explanatory” notes add extra help.
Adjectives and Adverbs – When Do We Add -ly?
We do not add “-ly” to these words. “Explanatorily” exists but is rare.
If you want to describe how someone explains, use a separate adverb. “She explained clearly.” “He explained patiently.”
This family stays simple. Focus on the verb and nouns.
Watch Out for Tricky Spelling Changes (Double Letters, y to i, and More)
Spelling here is very regular. No double letters. No y to i changes.
“Explain” adds “-ation” to make “explanation.” Keep the “n.” Explana + tion = explanation? Actually “explain” to “explanation” changes “ai” to “a.” Expl + anation. Better: write “explain.” Drop the “i” and add “ation.” Explan + ation = explanation.
“Explain” adds “-atory” to make “explanatory.” Explan + atory = explanatory.
“Explain” adds “-ed” to make “explained.” Just add.
No double letters.
Practice with your child. Write “explain.” Change to “explan,” add “ation.” You get “explanation.” Add “atory.” You get “explanatory.” Add “ed.” You get “explained.”

Tips for Parents – Help Your Child Learn Word Families in a Fun Way
Explain a game. “Let me explain how to play this card game.”
Give an explanation. “My explanation of gravity uses a falling apple.”
Use explanatory diagrams. “This chart is explanatory. It shows the water cycle.”
Use past tense. “Remember when I explained how plants grow?”
Play a game. You ask “Why?” Your child explains.
“Why is the sky blue?” “Because of how sunlight scatters.”
Draw a light bulb. Write “explanation” inside.
Read a book about curious questions. “The Book of Why” by Catherine Ripley.
Do not correct every mistake. If your child says “explain” for “explanation,” gently say “The explanation is what you say. You explain it.”
Celebrate when your child uses “explanatory.” That word makes them sound like a textbook.
Explain that explaining is teaching. “When you explain, you help someone understand.”
Tomorrow you will explain a recipe. You will write an explanation for a picture. You will use an explanatory chart. You will have explained something new.
Your child might say “You explained that so well.” You will feel proud.
Keep explaining. Keep giving explanations. Keep using explanatory tools. Keep remembering what you explained.
Your child will grow in language and in teaching skills. Explaining is the best way to learn. Words help us share knowledge.
