This guide will show you how to make the most of both tools, with real examples and tips to help you remember new words long term.

📘 What’s the difference between a dictionary and a thesaurus?

• Dictionary: Gives definitions, pronunciation, part of speech, and example sentences.

• Thesaurus: Suggests synonyms (similar words) and antonyms (opposite words), helping you expand your vocabulary.

🛠️ How to use a dictionary like a pro

1. Look Beyond the First Meaning
   Many words have multiple meanings. For example:

   • "Bright":

     • Meaning 1: giving off light (a bright room)

     • Meaning 2: intelligent (a bright student)
       ➤ Tip: Always read all the meanings, and focus on the context.

2. Check the Pronunciation
   Use the phonetic spelling and audio icon (in online dictionaries) to hear how native speakers pronounce the word.
   ➤ Example: “Schedule” is pronounced /ˈʃedjuːl/ in British English and /ˈskedʒuːl/ in American English.

3. Note the Word Form
   Dictionaries show if a word is a noun, verb, adjective, etc. Learn other forms:
   ➤ Example: Create (verb) → Creation (noun) → Creative (adjective)

4. Read Example Sentences
   These show you how to use a word naturally.
   ➤ Word: Benefit
   ➤ Example: “Regular exercise has many health benefits.”

🧠 How to use a thesaurus effectively

1. Find Better Words for Writing or Speaking
   Don’t just use the same words over and over.
   ➤ Example: Instead of “good”, try “excellent,” “pleasant,” “beneficial,” or “favorable.”

2. Understand Nuances
   Not all synonyms mean exactly the same thing.
   ➤ Example:

   • “Big” and “huge” are similar, but “huge” sounds much stronger.
     ➤ Tip: Always double-check with a dictionary to be sure the synonym fits the context.

3. Learn Antonyms to Strengthen Vocabulary
   ➤ Example:

   • Word: “Increase”

   • Antonym: “Decrease”
     ➤ Knowing both helps with reading comprehension and writing variety.

🧩 Practical tips to remember vocabulary long term

• Make Word Maps: Group new words with similar or opposite meanings.

• Create Flashcards: Write the word, definition, example, and synonyms.

• Use New Words in Sentences: The more you use them, the faster you’ll remember them.

• Review Often: Repetition over time helps move vocabulary to your long-term memory.

📝 Quick practice
