Alien words: what they are and why they matter

Alien words are made-up letter strings used in the Phonics Screening Check. About half of the 40 words in the check are alien words. They test pure decoding — your child can’t have memorised them, so they have to sound them out from the letters.

The full set of pseudo-words used in the check looks like phope, strume, or vight. They follow English spelling patterns but have no meaning. The DfE marks them on the page with a small alien icon to signal “this isn’t a real word; just sound it out”.

Why test made-up words?

Because the check is testing decoding, not memory. A child who has met “house” and “cat” a thousand times will recognise them on sight without doing any phonics work at all. That’s a useful reading shortcut, but it doesn’t tell us whether the child can read words they’ve never met before — which is the entire point of being literate.

A pseudo-word like phope can only be read by decoding: ph says “f”, o-e is the long-o split digraph, psays “p”. Add them up, you get “fope”. A child who can do that has demonstrably internalised the phonics system. A child who guesses “phone” hasn’t.

Why children find them harder

Two reasons. First, the absence of meaning is psychologically uncomfortable: children naturally try to make sense of letters. Second, alien words concentrate the trickier graphemes in unfamiliar combinations — strume is asking your child to handle a three-consonant onset and a split digraph in the same word.

How to practise alien words at home

1. Don’t read the word first. Show it. Say “have a go”. Wait.
2. Encourage segmenting. “Find the sounds. Sound by sound.” Many children try to guess based on word shape — they’ll say “phone” for phope. Gently redirect to letter-by-letter decoding.
3. Don’t penalise hesitation. A correct answer after thinking is a correct answer. The check has no time limit.
4. Praise the strategy, not the outcome. “Good — you sounded each bit out” is more useful than “well done, you got it right”.

Common pseudo-word patterns

The check rotates through a few favourite pseudo-word shapes. Knowing them helps:

• Section 1: CVC like vap, with a digraph swapped in for one letter (shup, chig, thab).
• Section 2: Split-digraph constructions (phope, strume, blane), trigraphs (vight, smight), and complex onsets (scrane, sploke).

Where alien words appear in the 2026 check

The 2026 Phonics Screening Check runs Monday 8 June to Friday 12 June 2026. Across those 40 words, expect roughly 20 pseudo-words (8 in Section 1, 12 in Section 2 in a typical year). The proportion has been broadly stable since 2012, so the patterns in our past-paper archive are a reliable guide to what your child will face. The pass mark for the whole check has been 32 out of 40, unchanged since 2012 — see our pass-mark guide.

Why we generate fresh alien words

Past papers are useful as a stress test, but the same pseudo-words shouldn’t be drilled — your child would just memorise them. Our app validates every generated alien word against an 8-layer pipeline (real-word check, profanity, homophone screen, phonotactic legality, complexity ceiling, ambiguity ceiling, visual similarity, and past-paper deduplication) so every word is novel and safe to put in front of a five-year-old.

The result: an effectively unlimited supply of fresh alien words shaped exactly like the ones in the real check. Five focused minutes a day on a different set of pseudo-words each session is the single most efficient preparation you can do — and the one schools find hardest to give every child individually. If you’d like to try it, open the app for a free 5-minute session, no signup needed.
