What does conception mean?
Conception has two principal meanings in modern English. In its biological sense, it denotes the moment when a sperm fertilizes an egg, marking the beginning of a pregnancy — a usage common in medicine, law, and everyday discussion. In its intellectual sense, it means the act of forming an idea, plan, or design in the mind, as well as the resulting notion itself: one may speak of the conception of a new policy, or describe a building as ambitious in conception. The word carries a somewhat formal register, lending weight to both physical and abstract contexts. Derived from Latin roots meaning 'to take in' or 'to receive', it shares ancestry with conceive and concept. Its versatility across scientific and creative domains makes it a valuable word for expressing beginnings — whether of life or of thought.
The fertilization of an egg by sperm; the start of a pregnancy.
"Advances in reproductive science have deepened our understanding of conception."
The act or process of forming an idea, plan, or design in the mind; an abstract idea or general notion.
"His conception of freedom differed sharply from his contemporaries'."
Often used in the phrase 'the conception of X' to mean how X is imagined or defined.
Used mainly for the intellectual sense (multiple ideas or understandings).
"Ancient cultures held very different conceptions of the universe."
Every human being you have ever met began life as a single cell at the moment of conception — yet 'conception' also describes every great idea that ever changed the world.

Etymology of conception
Conception derives from the Latin conceptio, meaning 'a comprehending' or 'a conceiving', formed from concipere, 'to take in, to receive, to become pregnant', itself from com- ('together') plus capere ('to take'). It entered English via Old French around the late Middle Ages, with the biological sense appearing early and the broader sense of mentally grasping or devising an idea developing alongside it. Cognates and related words include conceive, concept, deceive, and receive, all tracing back to the Latin root capere.
