1. When a comparison is made by using a comparative followed by ‘than’, the word ‘other’ must
exclude the thing compared from the class of things with which it is compared.
He is better than any man. (Incorrect)
He is better than any other man. (Correct)
‘Any man’ includes the man himself and thus the sentences will be awkward.
2. In some cases, the comparison is subtle and must be given proper attention.
Ex- The climate of Delhi is better than Mumbai. (Incorrect)
Here the comparison should be between the climate of Delhi and the climate of Mumbai.
The climate of Delhi is better than the climate of Mumbai. (Correct)
Or
The climate of Ranchi is better than that of Gaya. (Correct)
(Here, ‘That of’ means ‘the climate of’)
If the traits are in plural, it will be ‘those of’.
The products of Reliance are better than those of Suzuki.
