Concept and Conception

[Casiopea]

What is the differences between these two words?

In terms of thought, concept is the thing conceived, and conception is the process it undergoes.

concept
1556, from M.L. conceptum "draft, abstract," in L. "(a thing) conceived," from past participle of concipere "to take in". conception in the womb sense was c.1300.

Conception refers to taking in a idea or taking in a seed (i.e., become pregnant with knowledge or child). Concept refers only to abstract things, so it doesn't apply, or rather is not used to describe living things, such as children.

Thank you very much, Cas
I post it after I visited www.dictionary.com.
In conception entry, it includes all the meaning you mentioned, and abstract things. That is, it has a larger range of meaning than concept, including what concept means.
Here is the problem, Cas.
How would you choose?

You're welcome, Automoon.

It depends on context. What's the sentence?

There is not any specific question.
I wish you could tell me why do you use concept to mean abstract ideas, plan, thought, ect, while coneption also carries those meanings( I have checked it in www.dictionary .com of conception).
Why, do you not use concept?

As a final attempt, Automoon, I pray my last words on this subject will provide some comfort to you, and if not, well, you can't say we didn't try.

has no conception (i.e., lacks origin)
has no concept (i.e., lacks meaning)

I guess I didn't make myself understood clearly enough.
