definition of "articulate"

The primary definition of the verb "articulate" in The Britannica Dictionary is: to express (something, such as an idea) in words; in Collins Dictionary: When you articulate your ideas or feelings, you express them clearly in words.

The Collins version doesn't mention "clearly." Which one would you prefer?

I would hope it would be clear regardless.
