1. Suffixes:
* -ful: This is a very common suffix used to add the meaning "full of" or "characterized by".
* Example: "thank" becomes "thankful"
* -less: This signifies "without" or "lacking".
* Example: "hope" becomes "hopeless"
* -ish: This adds a sense of "somewhat" or "resembling".
* Example: "child" becomes "childish"
* -able: This indicates "capable of" or "suitable for".
* Example: "manage" becomes "manageable"
* -ous: This means "full of" or "characterized by"
* Example: "danger" becomes "dangerous"
2. Prefixes:
* un-: This negates the meaning of the base word.
* Example: "happy" becomes "unhappy"
* in-: This negates the meaning of the base word.
* Example: "accurate" becomes "inaccurate"
* im-: This negates the meaning of the base word, often before words beginning with 'm' or 'p'.
* Example: "possible" becomes "impossible"
3. Compound Words:
* This involves combining two words to create a new adjective.
* Example: "long" + "lasting" = "long-lasting"
Important Considerations:
* Meaning: Make sure the resulting adjective makes sense and is grammatically correct.
* Existing Words: Check if the word already exists as an adjective.
* Context: Consider the specific situation where you're using the adjective.
Examples:
* "The cat was very ______." You could use "playful," "fluffy," "curious," etc.
* "The movie was ______." You could use "thrilling," "sad," "boring," etc.
Word Formation is Complex:
* There are exceptions to these rules. Some words simply can't be made into adjectives using common methods.
* The English language is constantly evolving, so new adjectives are being created all the time.
Remember, creating adjectives is a creative process that involves understanding the meaning of words and the way they function in sentences.
