What Are Difficult Words in English?

Difficult words in English are those that are:

• Hard to spell (example: acquiesce)
• Hard to pronounce (example: anemone)
• Hard to understand because they’re rarely used (example: pulchritudinous)

Such words are uncommon in daily life, which is why they seem tough when you first encounter them. However, once you know their meanings and practice using them, they can become part of your active vocabulary.

Examples of difficult words in English:

• Pillory – To publicly shame someone
• Bedevil – To cause trouble continuously
• Truculent – Fierce or aggressive
• Peregrination – A long journey
• Pulchritudinous – Beautiful

What Makes a Word “Difficult” in English?

The difficulty of a word is often linked to:

1. Frequency of use – If you rarely see or hear a word, it feels unfamiliar (e.g., lampoon or omnipresent).
2. Spelling – Words with unusual letter combinations are harder to remember (e.g., anaesthetist).
3. Pronunciation – Some words look nothing like how they sound (e.g., yacht = yot).
4. Context – Some words are field-specific (medical, legal, scientific), which makes them harder outside their area.

For example, before COVID-19, words like quarantine or isolation were rare for most people. Now, they’re everyday terms.
