What is synthetic phonics?
Synthetic phonics teaches children to read by blending the sounds that letters make into whole words. It is the approach used in most English primary schools.
Children learn which sound — or phoneme — each letter or group of letters makes. They then learn to push those sounds together to read a word, and to pull a word apart into sounds in order to spell it.
"Synthetic" here has nothing to do with artificial. It comes fromsynthesising: combining separate sounds into a whole. A child who sees c-a-t and says each sound before running them together into "cat" is doing exactly what the method is named after.
Blending and segmenting
The two skills are the same operation in opposite directions.
- Blending is for reading: hearing or seeing the separate sounds and merging them into a word.
- Segmenting is for spelling: hearing a whole word and breaking it back into the sounds that make it.
A child often manages one before the other, and that is normal. Being able to read "shop" does not automatically mean being able to spell it.
Why schools use it
Systematic synthetic phonics is the approach recommended by the UK government and taught in most English primary schools. The argument for it is practical: it gives a child a method for an unfamiliar word rather than leaving them to guess from the picture or the shape of the letters. That is also where the confidence comes from — an unknown word becomes something to work out rather than something to be stuck on.
What this means at home
The most useful thing an adult can do is stay aligned with the order the school is teaching. Programmes introduce sounds in different sequences, and practising a sound the class has not reached yet is rarely helpful.
Pronunciation matters more than it sounds like it should. Sounds are said without an added "uh" — "mmm" rather than "muh" — because "muh-a-tuh" does not blend into "mat". If you are unsure how the school says a particular sound, ask; teachers are used to the question.
This is general guidance. The exact order, terminology and pronunciation depend on the programme a school has chosen, and the school's own guidance always takes precedence over anything here.
Where to go next
Understanding phonics phases explains how the sounds are grouped and roughly when each group is taught.
Bridging Phonics is a record and practice tool for adults. It is not a validated systematic synthetic phonics programme, it does not assess or diagnose a child, and it does not replace teaching from school or advice from a qualified specialist.
