Phonics: access to written words
Systematic phonics teaches children how speech sounds connect with letters and letter patterns, then how to use that knowledge for word reading and spelling. The Education Endowment Foundation’s current phonics review describes phonics as an important component of early reading and stresses explicit, systematic teaching matched to the child’s current knowledge.
Phonics has an important boundary: accurate decoding is not the same as comprehension or communication. EEF explicitly notes that phonics improves reading accuracy but does not necessarily improve comprehension on its own. A child therefore needs language, vocabulary and meaning-making alongside word-reading development.
Grammar: control of sentence meaning
Grammar helps a child show who did what, when something happened, whether something is singular or plural, how ideas are joined, and how meaning changes when sentence structure changes. Grammar is useful when it improves the child’s ability to understand, say and write sentences—not merely when the child can label nouns, verbs or tenses.
The UK Department for Education’s 2025 Writing Framework makes this distinction clearly: grammar knowledge helps pupils control sentences and convey meaning, but grammar taught in isolation does not by itself create writing fluency. Sentence construction, spelling, transcription, composition and meaning must ultimately work together.
Communication: using language with another person
Communication draws on listening, vocabulary, sentence formulation, idea organisation, turn-taking, audience awareness and the confidence to begin and repair a response. The EEF oral-language evidence review describes effective approaches as purposeful speaking and listening interaction, including adult modelling, scaffolding, vocabulary development, questioning and dialogue.
Communication therefore cannot be reduced to “confidence” alone. A child may want to speak but still need language structure. Another child may have strong sentence knowledge but speak less in a demanding setting. The underlying bottleneck matters.
