Please help me on this....

What exactly is a phase and phase shift? I want a complete

**intuitive**explanation because I am tired of reading explanations which explains phase/ phase shifts in terms of degrees and radians because it makes me hard to visualise phase physically.

I have read numerous content over it like.....

1.The time relationship between two or more signals in a circuit is called phase.

2.Phase is delay.

3.Phase shift is a ‘delay’

4.The phase is the timing of oscillations at some point.

5.The phase shift means the two signals will arrive at the receiving antenna, at two different times.

6.Phase is a frequency dependent time delay......and so on and so forth..

Can someone provide a singular theory about phase? so that I could conclude my findings above.

Thanks!
