Tricky double letters in English

What you’ll practice

Some English words follow clear double-letter patterns, while others are pure memorization—and this quiz blends both. You’ll train your eye for common doubles (like -rr-, -nn-, -mm-) and spot when a single letter is the correct choice.

Each question is multiple-choice with 4 options and no timer, so you can slow down and think through the spelling instead of rushing.

Difficulty and quiz setup

Difficulty is mixed by default, combining easier high-frequency words with tougher, less predictable spellings. You can also choose your preferred difficulty and question count before starting, making it ideal for quick drills or longer study sessions.

• Practice common double-letter traps (e.g., -cc-, -pp-, -gg-) in everyday words
• Learn to avoid “looks right” mistakes caused by pronunciation habits
• Strengthen proofreading skills for writing, schoolwork, and emails
• Build consistency with British vs. American variations when they appear
• Improve recall through repeated exposure to similar-looking options

Common pitfalls to watch for

A frequent mistake is doubling letters based on how a word sounds, even when the correct spelling stays single. Another trap is overcorrecting—adding an extra letter because you’ve recently seen it doubled in a different word.

Tips to score higher

When you’re unsure, compare the options letter-by-letter and look for familiar word chunks (like -tion, -ment, -ful) that often influence what comes before them. Replaying with a smaller question count can help you focus on patterns before moving back to mixed difficulty.
