Fruitful, productive, and profitable; bearing good results or abundant benefits.
From Latin fructuosus (fruitful, profitable), from fructus (fruit, profit, advantage). This adjective has been used in English since the 16th century.
Fructuous appears in Shakespeare and Donne—they used it to describe everything from harvests to love affairs that 'prove fructuous.' It's more elegant than 'productive' and carries hints of abundance, plenty, and reward, making it beloved by poets describing profitable ventures.
