Welcome to today’s vocabulary lesson focused on English affixes! If you’re looking to expand your word knowledge and speak English more fluently, understanding affixes is a powerful tool. This lesson is designed for B2 level English learners like you, focusing on practical ways to use affixes to improve your vocabulary and speaking skills. Let’s dive in and discover how mastering affixes can make a big difference in your English fluency!

What are Affixes and Why are They Important?

Affixes are word parts that are added to the beginning or end of a word to change its meaning. There are two main types of affixes:

• Prefixes: These are added to the beginning of a word. Think of them as ‘pre-‘ – before! For example, in the word “unhappy,” “un-” is the prefix.
• Suffixes: These are added to the end of a word. Think of ‘suff-‘ – after or following. For example, in the word “happiness,” “-ness” is the suffix.

Why are English affixes so important for vocabulary building and improving your spoken English? Because understanding them can dramatically increase the number of words you understand and can use! Instead of memorizing each word individually, you can learn a few common prefixes and suffixes and then understand hundreds of words by recognizing these parts. This is a smart way to improve English vocabulary efficiently.

Common English Prefixes: Expanding Your Word Power

Let’s explore some of the most common English prefixes. Learning these will help you decode the meaning of many new words and enrich your spoken English practice.

Examples of Common Prefixes

• un-: This prefix usually means “not” or “opposite of.”
  • Example: unhappy (not happy), uncomfortable (not comfortable), unusual (not usual)
  • Speaking Example: “I felt uncomfortable in the crowded room.”
• re-: This prefix often means “again” or “back.”
  • Example: rewrite (write again), return (come back), rebuild (build again)
  • Speaking Example: “Could you please repeat that? I didn’t hear you.”
• dis-: This prefix often means “not” or “opposite of,” similar to “un-“, but often used with different words. It can also mean “away” or “apart.”
  • Example: disagree (not agree), disappear (vanish, go away), disconnect (separate)
  • Speaking Example: “I disagree with your opinion on that matter.”
• im-/in-/il-/ir-: These are variations of prefixes that mean “not.” They are used before different starting letters to make pronunciation easier.
  • im- (before ‘m’, ‘p’, ‘b’): impossible (not possible), impolite (not polite)
  • in- (before most letters): incorrect (not correct), invisible (not visible)
  • il- (before ‘l’): illegal (not legal), illogical (not logical)
  • ir- (before ‘r’): irregular (not regular), irresponsible (not responsible)
  • Speaking Example: “It’s irresponsible to drive after drinking alcohol.”
• pre-: This prefix means “before” or “in advance.”
  • Example: prepare (get ready before), preview (view before), prehistoric (before history)
  • Speaking Example: “Let’s prepare for the presentation tomorrow.”
• mis-: This prefix means “wrongly” or “badly.”
  • Example: misunderstand (understand wrongly), misbehave (behave badly), misspell (spell wrongly)
  • Speaking Example: “I think you misunderstood my instructions.”

Common English Suffixes: Adding Nuance to Your Speech

Now, let’s explore some common English suffixes. Suffixes often change the grammatical function of a word (e.g., from verb to noun, or adjective to adverb) and add specific meanings. Understanding suffixes is crucial for both vocabulary building and accurate spoken English practice.

Examples of Common Suffixes

• -ly: This suffix usually changes an adjective into an adverb, often meaning “in a … way.”
  • Example: quickly (in a quick way), slowly (in a slow way), carefully (in a careful way)
  • Speaking Example: “Please speak slowly so I can understand.”
• -ing: This suffix often forms the present participle of verbs (used in continuous tenses) and can also create adjectives.
  • Example: walking (present participle of walk), exciting (adjective), interesting (adjective)
  • Speaking Example: “The movie was very exciting!”
• -ed: This suffix usually forms the past simple and past participle of regular verbs, and can also create adjectives.
  • Example: walked (past simple of walk), bored (adjective), interested (adjective)
  • Speaking Example: “I was bored during the lecture.”
• -tion/-sion/-ation/-ition: These suffixes often change verbs into nouns, indicating an action, process, or result.
  • Example: action (from act), discussion (from discuss), information (from inform), competition (from compete)
  • Speaking Example: “We need more information about this project.”
• -ment: This suffix also often changes verbs into nouns, often indicating a result or state.
  • Example: agreement (from agree), management (from manage), development (from develop)
  • Speaking Example: “We reached an agreement after the meeting.”
• -able/-ible: These suffixes mean “capable of” or “can be done.” They often form adjectives.
  • Example: readable (can be read), accessible (can be accessed), responsible (capable of responsibility)
  • Speaking Example: “This website is accessible on mobile phones.”
• -er/-or: These suffixes can indicate a person who performs an action or is associated with something, often changing verbs into nouns.
  • Example: teacher (person who teaches), actor (person who acts), director (person who directs)
  • Speaking Example: “My English teacher is very helpful.”
• -ness: This suffix changes adjectives into nouns, indicating a state or quality.
  • Example: happyness (state of being happy), kindness (quality of being kind), sadness (state of being sad)
  • Speaking Example: “Happiness is important for a healthy life.”

Affixes in Spoken English: Practical Application

Understanding affixes in spoken English is not just about recognizing words in reading or listening. It’s about actively using them in your own speech to express yourself more precisely and fluently. When you encounter a new word, try to break it down into its base word and affixes. This will help you understand its meaning and remember it better. Furthermore, using affixes correctly in your speaking makes you sound more natural and confident. It’s a key aspect of advanced English vocabulary and pronunciation.

For example, instead of just saying “I don’t agree,” you can use “I disagree,” showing a more nuanced understanding of negation. Instead of saying “He speaks in a slow way,” you can say “He speaks slowly,” using an adverb formed with a suffix. These small changes can significantly improve your English pronunciation tips and overall fluency.
