What does impregnate mean?
Impregnate is a verb with a primary meaning of making a person or animal pregnant. It also has a closely related figurative and technical meaning: to fill, saturate, or permeate something with a substance, quality, or influence. For example, resin can impregnate wood, while an idea may impregnate a person’s thinking. The word is more formal and specialized than common alternatives such as fill, saturate, or permeate, particularly in technical contexts. The reproductive sense is usually neutral, though it can sound clinical in medical or demographic discussion. Overall, impregnate conveys the idea of introducing something thoroughly into a substance or person, with the biological sense forming the starting point from which the other meanings developed.
