Five methods used to forming a words ?

1. Affixation: Adding prefixes or suffixes to a base word to create a new word. For example, adding "un-" to the word "happy" to create "unhappy."

2. Compounding: Combining two or more words to create a new word. For example, combining "snow" and "man" to create "snowman."

3. Conversion: Changing the grammatical form of a word to create a new word. For example, using the noun "hammer" as a verb to create "to hammer."

4. Blending: Combining parts of two words to create a new word. For example, combining "breakfast" and "lunch" to create "brunch."

5. Back-formation: Creating a new word by removing affixes from an existing word. For example, creating the verb "edit" from the noun "editor."

1. Affixation: Adding prefixes, suffixes, or both to a root word to change its meaning or part of speech.
2. Compounding: Combining two or more words into a single word with a new meaning (e.g., "doghouse," "bookstore").
3. Blending: Combining the beginnings and/or endings of two or more words to form a new word (e.g., "brunch," "spork").
4. Conversion: Changing a word from one part of speech to another (e.g., "to love" → "love," "a run" → "to run").
5. Acronymy: Forming a word from the initial letters of a phrase or group of words (e.g., "NASA," "RADAR").
