How to say "fertility" in Japanese
Choosing the right word
- 地力ちりょくnounThe fertility of soil or farmland — the natural productive power of the earth. Also used figuratively for a person's or organization's underlying strength.
- 豊沃ほうよくna-adjective, nounFertility as a quality of land: rich, productive soil. It describes the earth's capacity to bear crops, not the fertility of people or animals.
- 稔性ねんせいnounFertility of plants: their capacity to set seed. A technical term of botany and agriculture, so unless you read agronomic writing this is seldom the word you want.
- 妊性にんせいnounFertility in the reproductive sense, especially of animals — the capacity to conceive and bear young. A rare word; for this meaning it is seldom the one you need.
- 妊孕能にんようのうnounFertility as the capacity to conceive and bear offspring. A less common noun, found chiefly in medical writing about reproduction.
All five are less common: use 地力 or 豊沃 for the fertility of land or soil, 稔性 for plants, and 妊性 or 妊孕能 for fertility in the reproductive sense of conceiving offspring.
