Grapheme–phoneme correspondence Created 2026-10-25 Updated 2026-11-05
A grapheme–phoneme correspondence links a written unit with a speech-sound unit. One grapheme can contain several letters, so correspondence is not necessarily a one-letter-to-one-sound rule. The mapping can depend on context and competing patterns in a writing system. Learning useful mappings supports phonological recoding, while recognizing the spoken form of a word is only one contribution to understanding a text. [ref]
