Sounds and spellings

When are split digraphs taught?

Split digraphs are introduced in Phase 5 of Letters and Sounds. A digraph is two letters making one sound; in a split digraph another letter sits between them.

Phase 5. There are five, and they are usually taught together as a set.

• a–e — make, cake, name, gate
• e–e — these, theme, complete
• i–e — time, bike, ride, smile
• o–e — home, bone, note, rose
• u–e — cube, tube, huge, rule

What "split" means

A digraph is two letters standing for one sound — ai, ee, oa. In a split digraph the two letters do the same job, but a consonant has come between them.

In cake the sound is made by the a and thee working together, with the k sitting in the middle. The word has four letters and three sounds:c — a–e — k. Thee is part of the vowel spelling, not a separate sound and not decoration.

Why not "magic e"?

Many adults were taught the idea as a silent or magic e that reaches back and changes the vowel. It is a memorable image and it gets the right answer, but it describes the spelling as a trick rather than as a pattern.

Describing it as a split digraph keeps it consistent with everything else a child has learned: two letters, one sound, exactly like aior oa — just not next to each other. If a child has been taught the split digraph name at school, using "magic e" at home introduces a second vocabulary for one idea, which rarely helps.

Why this is Phase 5 and not earlier

A split digraph asks a reader to look further ahead than any earlier spelling does. Up to this point, sounds have been read left to right in order. Here the reader has to notice a letter at the end of the word before deciding what a letter near the beginning says — hop andhope differ only in that final letter.

That is a genuine step up in what the reader is doing, not just another spelling to memorise, which is why it sits alongside the other Phase 5 alternatives rather than with the Phase 3 digraphs.

A note for checking texts

Words containing split digraphs often look simple — make, time, home are short, everyday words — so they slip into material intended for earlier phases without anyone noticing. Every letter incake appears in Phase 2, but the word itself needs Phase 5.
