Today, let’s learn some English that may help you increase your vocabulary.

Learning Vocabulary More Effectively

Many English learners often say:

“It’s really hard to master vocabulary.”

That feeling is understandable. There are countless English words, and learning new vocabulary takes time, repetition, and practice.

However, if you learn a few useful patterns, building your vocabulary can become much easier and more natural.

One of the best ways to improve vocabulary is by learning prefixes.

What Is a Prefix?

A prefix is a group of letters added to the beginning of a word.

Understanding prefixes can help you guess the meaning of unfamiliar words, improve reading comprehension, and remember vocabulary more efficiently.

Instead of memorizing words one by one, you can learn how words are connected.

Today’s Prefix: dis-

There are many prefixes in English, and today we will focus on dis-.

The prefix dis- often means:

• not
• opposite of
• away from

When you understand this prefix, many words become easier to recognize and understand.

Examples of Words with dis-

dislike
→ to not like

disagree
→ to have a different opinion

disobey
→ to refuse to follow rules or orders

disappointment
→ sadness when something is not as hoped

By learning one prefix, you can understand many useful English words more quickly.

Study Tip
Instead of trying to memorize every word separately, study prefixes, suffixes, and word roots.
This helps you build vocabulary faster and understand English more deeply.
Even small steps every day can lead to big improvement.
Consistency is one of the most important keys to success in language learning.
Keep Learning Little by Little

English improvement does not happen overnight, but steady practice creates real progress.

Keep studying, keep reviewing, and keep enjoying the process.
