"The culture that/in which we inhabit..."

Question

The culture that we inhabit shapes how we think, feel, and act in the most pervasive ways.

The culture in which we inhabit shapes how we think, feel, and act in the most pervasive ways.

Is either of them wrong in some way?

Answer 1

The first is correct; the second uses 'inhabit' incorrectly. Inhabit is a transitive verb, that is to say, we inhabit a place; we do not inhabit in a place, so cannot say 'in which we inhabit'.

inhabit verb [ T often passive ]
C2

to live in a place:
These remote islands are inhabited only by birds.
