Learner spells noun forms that transform rather than simply add a suffix, which produces invented words at Band 5.

Eight noun forms. Four are real English. Tick the ones you believe.
Most nouns you assemble. These ones you cannot — the word changes inside.
Most of the time, building a noun is addition. You keep the word and put something on the end.
govern + ment → government
achieve + ment → achievement
treat + ment → treatment
Nothing moves. Nothing disappears. If all English worked like this, spelling would be easy.
But a second group transforms. The word changes on the inside, and no amount of careful adding will get you there:
describe → description (the B becomes a P)
explain → explanation (the I disappears)
repeat → repetition (the EA becomes E)
choose → choice (barely recognisable)
This matters because a learner who does not know a word is in the second group will build it anyway — and produce describtion, explaination, repeatition. Those are not sloppy errors. They are the sound of someone applying a rule correctly to a word that does not obey it.
Watch each verb become its noun. The marked letters are the ones that move.

These nouns are not built by adding. The word changes inside.
Eight verbs, eight nouns — and four of the nouns on offer do not exist.
