can anyone help me differ "Perception" from "Conception"? any reply will be greatly appreciated.thank you!

I assume you have already looked in your dictionary? Here are a couple of general guidelines.

Perceive relates to seeing, to noticing.

eg I perceived a movement at the window. I perceived that he was lying to me.

Conceive relates to originating something, often in your mind.

eg I conceived an idea. I conceived a plan.

Best wishes, Clive

By perception we mean the mental activity of appreciating our sensory experiences like hearing the lecture of the teacher, looking at the emerging sun, feeling the warmth of touch and so on, whereas a conception is something or somebody or some event held as an idea in our long term memory formed through past perceptions, like a soccer, an accident, garments, etc.
