  • fertile land
  • fertile ground

  • fertile farmland
  • fertile fields
  • fertile plains
Synonyms

Common Mistakes

The plant is very fertile.
The soil around the plant is very fertile.

  • barren

    Especially used for female animals (or poetic use for people) that cannot bear young.

Usage Note

Can apply to humans, animals, and plants, but for plants the meaning overlaps with sense 1 (good soil producing plants). To avoid confusion, use this sense specifically when the subject is the creature or plant itself, not the ground it grows in.

Common Mistakes

The soil is fertile enough to grow plants.' (using sense 2's definition of producing young/fruit).
The soil is fertile enough to support plant growth.

Synonym discussion

Sense: adjective/1

All five words describe land or situations that yield good results, but they differ in emphasis and use. 'Fertile' (B2) is the most neutral and widely used term for soil that contains enough nutrients to grow crops well. 'Productive' (B2) focuses on the actual output — a farm can be productive even if its soil is only moderately fertile, because good farming methods can compensate. 'Fruitful' (B2) is slightly more formal and often used metaphorically: 'a fruitful discussion' means it produced useful results, while 'fertile ground for discussion' means the conditions were right. 'Rich' (A2) is less formal and describes soil that looks dark and feels full of organic matter. 'Lush' (B2) focuses on what grows above the ground — lush vegetation is thick and green, but the soil underneath might be only moderately fertile. For example: 'The fertile soil of the Nile Valley has supported agriculture for thousands of years' (neutral and precise about the soil's capacity). 'Nut trees grew best on the rich, dark earth near the stream' (describes the appearance and feel of the soil). The key difference: fertile = the land's capacity to support growth; productive = the actual harvest; fruitful = the beneficial results; rich = the visible quality of the soil; lush = the thick vegetation that results.

Etymology

LatinFrenchEnglish

The word 'fertile' comes from Latin 'fertilis', meaning 'bearing abundantly, fruitful', which itself comes from 'ferre' meaning 'to bear or carry'. The word entered English in the 15th century through Old French 'fertile'. The metaphorical uses (for the mind, imagination, or a situation full of possibilities) developed in the 16th and 17th centuries, extending the original agricultural meaning.
