5 important tips on how to improve your spelling skills
Spelling myth 1: -tion, -sion, -cion and -ssion

Many popular spelling schemes teach -tion, -sion, -cion and -ssion as four different suffixes, with spelling rules and exceptions for their use. These are incorrect and overwhelming for learners.
Fact
Our scheme teaches learners how to spell one suffix: suffix -ion.
And the letters t, s and c? These letters will be part of the other morphemes that create the word.
-
act + ion = action
-
re + vis
e+ ion = revision (drop the final “e” from “vise”) -
su + spic
e+ ion = suspicion (drop the final “e” from “spice”) -
ob + sess + ion = obsession
Spelling myth 2: -cious and -tious

Many popular schemes teach -cious and -tious as two different suffixes, with spelling rules and exceptions for their use. These separate suffixes do not exist and can be overwhelming for learners.
Fact
Our scheme teaches learners how to spell suffix -ous, which always carries the meaning “full of”. We use the connecting vowel letter i to join the morphemes, smoothing the pronunciation.
And the letters t, and c? These letters will be part of the other morphemes that create the word.
-
spac
e+ i + ous = spacious (drop the final “e” from “space”) -
in + fect + i + ous = infectious
Spelling myth 3: i before e except after c

This is a well-known rule, created in the 1800s to help children remember the spelling of some words, but it oversimplifies the system. In fact, it is wrong more than twenty times as often as it is right!
Fact
The letter pattern cei appears in English in one word family, which ultimately comes from the Latin root capere: bases ceive and ceipt, which carry the meaning of “take, seize or hold”. When we teach the spelling of these two bases and words in their family, we teach how this cei letter pattern really works in English, in words such as receipt or inconceivable.
Exceptions (“ei” without a “c”):
- weigh, eight, vein, veil, sleigh, height, either, neither, Einstein, weird, leisure, species, science
Exceptions after “c” (using “ie” instead of “ei”):
- ancient, deficient, sufficient, species, proficient, conscience, glacier, and more!
Spelling myth 4: sounding out all words

Phonically regular words can be sounded out in their entirety, but for most words, this approach only gets you part of the way—because English spelling also preserves meaning and history, not just sound.
Fact
English spellings reflect not just sounds (phonology), but also word parts and meanings (morphology) and word histories (etymology).

Spelling myth 5: -cial and -tial

Many popular schemes teach -cial and -tial as two different suffixes, with spelling rules and exceptions for their use. These separate suffixes do not exist and can be overwhelming for learners.
Fact
Our scheme teaches learners how to spell suffix -al, which always carries the meaning “action, process or related to”. We use the connecting vowel letter i to join the morphemes, smoothing the pronunciation morphemes that create the word.
And the letters t and c? These letters will be part of the other morphemes that create the word.
-
part + i + al = partial
-
of + fic
e+ i + al = official (drop the final “e” from “fice”)
A must for primary teachers
With the Department for Education’s Writing Framework (July 2025) now calling for the systematic teaching of morphology, a dictionary of morphemes is an invaluable resource for primary classrooms, supporting spelling, vocabulary development and reading comprehension through meaningful exploration of the English language. Books like The Big Book of Morphemes can offer learners deeper insight into the journeys words have taken through time and languages.
