You talk with a friend about a movie. You share opinions. You listen.
That is discussion. Today we learn four words.
“Discuss,” “discussion,” “discussable,” and “discussed.”
Each word shares the idea of talking together. Each does a different job.
Parents and children can learn these words together. They help with conversation.
What Does “Same Word, Different Forms” Mean?
One action takes different shapes. The action here is talking about a topic.
“Discuss” is a verb. “Let us discuss our plans for the weekend.” Action.
“Discussion” is a noun. “The discussion lasted an hour.” Talk.
“Discussable” is an adjective. “This topic is discussable at dinner.” Describes.
“Discussed” is a past tense verb or adjective. “We discussed the rules.” Past action. “The discussed idea.” Describes.
Same root. Different endings. Different jobs. The talking stays.
Personal Pronouns Change Their Form
Pronouns change for grammar. “I” becomes “me.” “We” becomes “us.”
Our words change for role and time. “I discuss my feelings.” Present.
“The discussion was helpful.” Noun. “That is discussable.” Describes.
“We discussed it yesterday.” Past.
Pronouns help us speak faster. Word families help us talk about sharing ideas.
When children know these four words, they join conversations.
From Verb to Noun to Adjective to Adverb – One Family, Many Words
“Discuss” is a verb. “Discuss the book with your partner.” Action.
“Discussion” is a noun. “The class discussion was lively.” Talk.
“Discussable” is an adjective. “A discussable issue is open to talk.” Describes.
“Discussed” is a past verb. “They discussed the movie.” Past action.
“Discussed” is also an adjective. “The discussed topic was sensitive.” Talked-about.
We have an adverb “discussably” (rare). Skip it.
Five members. Very useful for school and home.
One Root, Many Roles – How Words Grow from Actions to Qualities
The root “discuss” comes from Latin “discutere,” meaning to shake apart. “Dis-” apart + “quatere” to shake. To shake out ideas.
From that root, we add “-ion” to make a noun. “Discussion” means the act of talking.
We add “-able” to make an adjective. “Discussable” means suitable for discussion.
We add “-ed” for past tense or to make an adjective meaning “talked about.”
Help your child see this pattern. Discuss is the action. Discussion is the event. Discussable means can be talked about. Discussed means already talked about.
Same Meaning, Different Jobs – Is It a Verb or a Noun?
Look at “discuss.” Always a verb. “Let us discuss the problem.” Action.
“Discussion” is always a noun. “The discussion was respectful.”
“Discussable” is always an adjective. “Is that topic discussable?”
“Discussed” can be a past verb or adjective. “We discussed the issue.” Past verb. “The discussed points were important.” Adjective.
Teach children to look at the endings. “-ion” noun. “-able” adjective. “-ed” past verb or adjective.
“Discuss” alone is the present verb.
Adjectives and Adverbs – When Do We Add -ly?
We add “-ly” to “discussable” to make “discussably.” Very rare. “The topic is discussably complex.” Skip it.
We do not add “-ly” to “discuss,” “discussion,” or “discussed.”
For children, skip these adverbs. Focus on the main words.
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.
“Discuss” has double “s.” D-I-S-C-U-S-S. Keep double “s” in all forms.
“Discuss” adds “-ion” to make “discussion.” Keep double “s.” Discuss + ion = discussion. (Drop the “s”? No, keep both “s”s.)
“Discuss” adds “-able” to make “discussable.” Keep double “s.” Discuss + able = discussable.
“Discuss” adds “-ed” to make “discussed.” Keep double “s.” Discuss + ed = discussed.
No dropping. Very clean.
Practice with your child. Write “discuss.” Add “ion.” You get “discussion.” Add “able.” You get “discussable.” Add “ed.” You get “discussed.”
Double “s” in all forms.
