1. She likes summer and others like winter.
2. She likes summer and the others like winter.
(Are both grammatical?)
3. The dog and the cat don't like each other.
(Does the dog or the can mean the specific dog and the specific cat? Or were they used in generic term? Do all dogs and all cats hate one another?)
1 and 2 are both grammatically correct.
The definite article "the" IS specific. A/An is the indefinite article and non-specific.
No, not all dogs and cats hate each other!
