Comparison with "the ... the" structure

Question

I just wonder the following sentence is correct or not: "The better the weather is, the better we feel." since I usually hear things like: "The better the weather, the better we feel." Many thanks

Answer 1

• (1) The better the weather is, the better we feel.
• (2) The better the weather, the better we feel.

Sentences (1) and (2) are both grammatically valid, and have the same meaning. A fluent speaker might well use either, and would understand either. Sentence (2) could be considered a shortened form of (1). Such constructions are common.

Answer 2

Yes, that is perfectly natural and common too.

For example,

...the better the work is the less visible it is...

...the better the work is the better it sells.

...the higher the pressures are, the better the prognosis is.
