It is called Inverting Amplifier because the op-amp changes the phase angle of the output signal exactly 180 degrees out of phase with respect to input signal. Same as like before, we use two external resistors to create feedback circuit and make a closed loop circuit across the amplifier.

What is the meaning of inverting amplifier?
An inverting op amp is an operational amplifier circuit with an output voltage that changes in the opposite direction as the input voltage. In other words, it is out of phase by 180o。
Why the inputs of op-amp are called inverting and non-inverting?
In a non-inverting amplifier, the input signal is applied at the positive (called non-inverting) terminal. In the inverting amplifier, there is a phase difference of 180° between the input signal and output signal. Hence, the input and output signals are out of phase in case of an inverting amplifier.
What is an inverting?
to turn upside down. to reverse in position, order, direction, or relationship. to turn or change to the opposite or contrary, as in nature, bearing, or effect: to invert a process. to turn inward or back upon itself.
What makes an op-amp inverting?
The op-amp inverting configuration, like the non-inverting configuration, requires only one operational amplifier and two resistors. The inverting configuration creates a negative gain, meaning that one circuit can both amplify a signal and change its polarity from positive to negative or negative to positive.
