[Grammar] I know you wouldn't do this if you didn't think it safe

[Ferdie11]

Hi,

Is this sentence grammatically correct?

I know you wouldn't do this if you didn't think it safe.



I think it should be:

I know you wouldn't do this if you didn't think it was safe

Many thanks.

The first sentence is fine. The "was" is understood by the reader.
