Mixed Practice — One/Ones, Another, The Other, Others, Each Other
Challenging exercises combining all five forms: one/ones, another, the other/the others, other/others and each other. Difficulty 3 error-correction, text-correction and transformation tasks.
Mixed Practice: Choosing Between All Five Forms
Once each form is studied in isolation, the real challenge is discrimination in context — choosing among one/ones, another, the other/the others, other/others, and each other when multiple options seem plausible. Errors in mixed contexts tend to cluster around three pairs: another vs the other (open vs closed set), others vs the others (general vs specific group), and each other vs reflexive pronouns. At difficulty 3, exercises include text-correction tasks that require identifying two errors in a single passage — the most challenging format for discrimination training.
Decision Guide
Replacing a noun (plural): ones — 'Have you got cheaper ones?'
One more / a different (singular): another — 'Another cup, please.'
The remaining one of a pair: the other — 'One sister is in London; the other is in Paris.'
The remaining specific group: the others — 'Two left; the others stayed.'
Other/additional (before noun): other — 'Any other questions?'
Other people in general: others — 'Some like tea; others prefer coffee.'
Mutual action: each other — 'They help each other every day.'
Common Mistakes
✗ I'd like to see another colours. → ✓ other colours. (plural noun — not another)
✗ I want to try the another. → ✓ the others. ('the another' is impossible)
✗ My brother and I haven't spoken to ourselves since the argument. → ✓ each other. (mutual, not reflexive)
✗ The other studied hard but failed. (= the remaining students) → ✓ The others studied hard but failed.
