Welcome to our first lesson on Vocabulary Development! Today, we’ll be discussing Word Formation. This is an essential part of understanding and expanding your vocabulary in English. Let’s explore how words are created, changed, and used to express different meanings.

What is Word Formation?

Word Formation refers to the process of creating new words or modifying existing ones by adding prefixes, suffixes, or combining words. It’s like building blocks – we take a base word and change it slightly to create new meanings!

For example:

• Happy becomes unhappy by adding the prefix un-.
• Teach becomes teacher by adding the suffix -er.

Types of Word Formation

There are several ways new words are formed in English. Let’s explore the most common ones!

1. Derivation
2. Compounding
3. Conversion
4. Clipping
5. Blending
6. Acronyms and Abbreviations

1. Derivation

Derivation is one of the most common ways to form new words. It involves adding prefixes (before the root word) or suffixes (after the root word) to create a new word with a different meaning.

• Prefix: A group of letters added to the beginning of a word.
  Examples:
• Dis + appear = Disappear
• Un + known = Unknown
• Suffix: A group of letters added to the end of a word.
  Examples:
• Care + ful = Careful
• Read + able = Readable

Common Prefixes and Their Meanings:

Prefix	Meaning	Example
un-	not	unhappy (not happy)
re-	again	rebuild (build again)
dis-	opposite of	disagree (not agree)
pre-	before	preview (view before)
mis-	wrongly	misunderstand (understand wrongly)

Common Suffixes and Their Meanings:

Suffix	Meaning	Example
-er	one who	teacher (one who teaches)
-ness	state or quality	happiness (state of being happy)
-able	capable of being	readable (capable of being read)
-ment	action or process	improvement (the process of improving)
-ful	full of	joyful (full of joy)

2. Compounding

Compounding involves combining two or more words to create a new word. These words can be written as one word, hyphenated, or separate words.

• Examples:
• Blackboard (black + board)
• Toothpaste (tooth + paste)
• Mother-in-law (mother + in + law)

3. Conversion

Conversion is changing the word class without changing the form of the word. For example, a noun can be used as a verb.

• Examples:
• Noun to Verb:
  • Google (noun) -> to google (verb)
  • Email (noun) -> to email (verb)

4. Clipping

Clipping is the shortening of a longer word, usually to make it more informal or conversational.

• Examples:
• Telephone -> Phone
• Laboratory -> Lab
• Photograph -> Photo

5. Blending

Blending is combining parts of two or more words to form a new word, often taking the beginning of one word and the end of another.

• Examples:
• Smoke + Fog -> Smog
• Breakfast + Lunch -> Brunch
• Motor + Hotel -> Motel

6. Acronyms and Abbreviations

• Acronyms are formed from the initial letters of a phrase, creating a new word.
• NASA: National Aeronautics and Space Administration
• AIDS: Acquired Immune Deficiency Syndrome
• Abbreviations shorten a word by cutting off some of its letters.
• Dr. for Doctor
• Feb. for February

Practice Exercise:

1. Convert the following words by adding prefixes or suffixes:
   • Like -> __
   • Manage -> __
   • Able -> __
2. Combine these words using compounding:
   • Foot + Ball -> __
   • Sun + Flower -> __
3. Identify the type of word formation for the following:
   • Laptop (Laptop: __)
   • Info (Information: __)
   • Radar (Radio Detection and Ranging: __)

Conclusion:

Understanding Word Formation helps in building your vocabulary and improving your ability to communicate more effectively in English. By mastering these methods, you will be able to recognize and create new words, understand their meanings, and use them confidently in your writing and speech!

Homework:

• Find 5 words each that use prefixes, suffixes, compounding, conversion, clipping, and blending.
• Write sentences using each word to show how they can be used in context.
