In electronics, direct coupling or DC coupling (also called conductive coupling) is the transfer of electrical energy by means of physical contact via a conductive medium, in contrast to inductive coupling and capacitive coupling.

What is meant by directly coupled?

1 of belting or gearing : coupled without intermediate connections. 2 of an electric circuit : having conductive rather than inductive or capacitive coupling.

What is direct coupled in op amp?

OPAMP is called direct coupled because the input of one OPAMP is inserted into the input of another OPAMP. It is called high gain differential circuit because the difference of the two input is amplified.
