Tricky Letter Combinations

Why are these words hard?

Some letter groups sit right next to each other on the keyboard or are typed with the same finger in a row, which slows you down and raises your error rate. English words with clusters like “str”, “ght”, and “thr” are classic examples.

How should you practice?

• Type these words slowly the first time and focus on accuracy.
• If you notice a specific letter pair trips you up, drill just that pair on its own (e.g. “th th th”).
• Over time these combinations become automatic, and your overall speed will noticeably improve.
