arun@crackverbalHow do we decide as to when is it okay to omit words in questions related to comparisons?
Example: The doctors of city hospital are more dedicated than other hospitals.
Now, I understand the statement is incorrect because the doctors are being compared to hospitals.
But, how do I know it is not a case of omitted words?
The sentence can be - The doctors of city hospital are more dedicated than ("the doctors of" or "those of") other hospitals.
Thanks for asking me!
Remember - what we teach in ellipsis

The omission cannot introduce ambiguity.
In the tug-of-war between concision (which demands as few words as possible) and clarity (which demands specificity) - always pick clarity.
So tell me if this makes sense:
I can run faster than my brotherIt does!
You don't need to say:
I can run faster than my brother can runNow, let us look at another example:
Amit loves Alia more than his wife.This is wrong because it can lead to multiple interpretations:
Amit loves Alia more than (he loves) his wife.
Amit loves Alia more than his wife (loves Alia).
Also, we are talking about verb ellipsis.
Your example is incorrect because even with noun ellipsis you need to have a possessive or a "that of" / "those of" (demonstrative pronoun) structure.
The doctors of city hospital are more dedicated than other hospitals
The correct form would be:
The doctors of city hospital are more dedicated than those of other hospitals.
Note that the same can also be rewritten as:
The dedication of doctors in City hospital is more than that of other hospitals.
Let me know if this helps,
