Common Two-Letter Combos (Bigrams)
th · he · in · er · an
A bigram is a two-letter sequence. A small set of them — TH, HE, IN, ER, AN, RE — makes up a huge share of English, and fluent typists hit them as a single motion rather than two separate keys.
Type pairs, not letters
Beginners type one letter at a time. Fast typists chunk: TH and HE fire as practiced little rolls. Drilling common bigrams is how those rolls form.
keyspraut samples these high-frequency pairs directly from a real text corpus, so the combos you practice are the ones you actually meet.
Tip: Aim to feel TH, HE and IN as one motion, not two keystrokes.
