Grammarsaurus – The Big Book of Morphemes

Grammarsaurus – The Big Book of Morphemes is a comprehensive dictionary designed to empower learners to spell with understanding, rather than through guesswork. Ideal for children with literacy difficulties, this go-to resource assists with building vocabulary and strengthens comprehension through word structure.

English is a morphophonemic language, meaning it’s built on both sounds and meaningful word parts, yet most spelling instruction stops at the phonemic. With clear visuals, accessible definitions and dual coding to aid memory, Grammarsaurus – The Big Book of Morphemes helps children make lasting connections between spelling, meaning and vocabulary.

With the Department for Education’s Writing Framework (July 2025) now mandating that schools teach morphology systematically, Grammarsaurus – The Big Book of Morphemes is essential for all primary school teachers. When exploring morphology, both teachers and children can use this book to look up a word’s meaning and origin: whether Latin (L), Ancient Greek (AG), Old English (OE), or Unknown (UKn), and see how it contributes to the formation of other words, supporting spelling, vocabulary and reading comprehension.
