Word Formation
Change Words Across Parts of SpeechTurn nouns into adjectives, verbs into nouns, and more!
📖 Let’s Learn Word Formation!
In Grade 3, you learned about root words, prefixes, and suffixes. Now in Grade 4, let’s learn how to change a word from one part of speech to another! For example: beauty (noun) → beautiful (adjective) → beautifully (adverb).
Word formation is like magic — one root word can become a noun, verb, adjective, or adverb depending on what ending you add. This skill helps you write more flexibly and score higher in vocabulary tests!
💡 The Rule
Words can change their part of speech by adding suffixes:
Noun → Adjective: beauty → beautiful
Adjective → Adverb: beautiful → beautifully
Verb → Noun: act → action
Adjective → Noun: kind → kindness
🎯 Key Concept
🏗️ Base word: BEAUTY (noun)
→ beautiful (adjective) = full of beauty
→ beautifully (adverb) = in a beautiful way
→ beautify (verb) = to make beautiful
📋 Word Formation Patterns
-ful, -ous, -al, -ive: beauty→beautiful, danger→dangerous
Add -ly: slow→slowly, happy→happily, beautiful→beautifully
-tion, -ment, -er: act→action, enjoy→enjoyment, teach→teacher
-ness, -ity: kind→kindness, happy→happiness, curious→curiosity
-ify, -ize, -en: beauty→beautify, modern→modernize, strength→strengthen
-able, -ive, -ful: enjoy→enjoyable, act→active, help→helpful
