Digraph

Definition

A digraph is a pair of letters that together spell one sound, such as CH, SH, TH, PH, or CK. Digraphs are extremely common in English and behave as single units when reasoning about words.

Why it matters

Spotting a likely digraph from a clue lets you place two letters at once and recognise common word shapes faster.

Examples

• CH in CHASE.
• TH in THINK.

Best practices

• Treat digraphs as single sound-units.
• Watch for them at word starts and ends.
