Morphology
fraction = fract + ion
Formed from the combining form 'fract-' + '-ion', but 'fract' is not a standalone English word so learners cannot reliably infer the technical meaning from the components.
Etymology
Fraction comes from an old Latin word frangere meaning 'to break' and the short root fract appears in words like fragment. In science, a fraction is a part 'broken off' and collected when a mixture is separated.
