1. Compounding

Compounding involves joining two or more separate words to create a new word. The resulting compound word has a meaning that relates to both original words.

Examples:

• fire + man → fireman
• rain + bow → rainbow
• class + room → classroom
• note + book → notebook
• home + work → homework

2. Blending

Blending combines parts of two or more words to form a new word. Usually, the beginning of one word joins with the end of another word.

Examples:

• smoke + fog → smog
• breakfast + lunch → brunch
• motor + hotel → motel
• telecommunication + network → telenet

3. Clipping

Clipping shortens a longer word by cutting off part of it while retaining the core meaning.

Examples:

• advertisement → ad
• laboratory → lab
• examination → exam
• photograph → photo
• kilogram → kilo

4. Conversion (Functional Shift)

Conversion changes a word from one word class to another without changing its form. A noun becomes a verb, or vice versa.

Examples:

• book (noun) → to book (verb)
• water (noun) → to water (verb)
• empty (adjective) → to empty (verb)

5. Derivation

Derivation involves adding prefixes or suffixes to a base word to create a new word with a different meaning.

Examples:

• happy → unhappy (prefix: un-)
• care → careless (suffix: -less)
• act → action (suffix: -tion)
• possible → impossible (prefix: im-)

6. Coinage

Coinage creates entirely new words, often for new products or concepts. These words typically have no connection to existing words.

Examples:

• google (search engine)
• Kodak (brand name)
• aspirin (medicine)

7. Borrowing

Borrowing takes words from other languages and incorporates them into English.

Examples:

• bwana (Swahili) → used in East African English
• safari (Swahili) → used globally
• champagne (French)

When forming new words, consider which process best suits the context and the meaning you want to convey.

Worked Example from Textbook

Using the base word FLY, form a word that fits the sentence: "How long is the __________ from Dar to Mwanza?"

• The base word: FLY
• Required meaning: the action or process of flying
• Appropriate suffix: -ing (conversion from noun to gerund)
• Result: flight

Complete sentence: How long is the flight from Dar to Mwanza?

1. Identify the required word class (noun, verb, adjective, adverb) from the sentence context.

2. Choose the appropriate process based on the meaning you need to convey.

3. Check spelling — word formation often changes spelling (e.g., "happy" → "happiness," not "happyness").

4. Verify meaning — the new word must make logical sense in the sentence.

In everyday life in Tanzania, word formation helps you understand and create new terms you encounter in business, media, and communication. For example, when running a m kiosk (duka) in Dar es Salaam, you might blend "mobile" with "kiosk" to describe a mobikiosk — a small shop that uses mobile money services. Understanding processes like compounding and clipping also helps you recognize abbreviations common in Tanzanian commerce, such as M-Pesa (where "Pesa" is Swahili for money), and use them correctly when discussing transactions or budgeting with customers.
