Can an adjective "robust" be a noun in a sentence? And if it can't how would you say with one word "robust fellow" that can be applied to both man and woman? Because as I understand "robust fellow", we say about a man.

    In the same way that we say, "Youth is wasted on the young," we might say "Only the robust should attempt this hike." But a "robust person" or "robust worker" or something else that makes sense in context could work.

    We can use the definite article to refer to a class. Thus: the robust = "those who are robust" (gender not specified). This technique works in a general way for adjectives most of the time. HTH.

    @Kris But if I am talking about one specific person it doesn't seem to me right to say "He is the robust". What one-word synonym in English language could replace word-combination written above?

    One should work. "He is the robust one."

"robust" is an adjective and it could only be used as a noun when you refer to a class ("the robust") just as you say "the poor", "the rich", "the wealthy". Other adjectives that have a similar meaning are "sturdy", "able-bodied" and "stocky".

  • robust (adj) - strongly formed or built. MW
  • stocky (adj) - compact, sturdy, and relatively thick in build.
  • sturdy (adj) - strong and healthy

These words can be used for both males and females, but I don't think a woman would like to be referred to as "stocky" or "robust".


I would use "stout."

: thick and strong

: physically or materially strong

You could also use "hearty."

: strong, healthy, and active

  • That's not quite the question we have at hand. Please review the question.

  • Actually, this is a part of the question. But as @plmadding wrote definition of "stout" is "thick and strong". And definition of "robust" is "healthy and strong". This two words don't seem like synonyms to me. Or am I wrong?

  • They are similar but not exactly the same. I mentioned them both because I don't know exactly what context you will use the word. Hearty is a word used to describe women frequently here, in Kansas. Especially women who have grown up on or currently live on farms.
