aqueous solution - What is meant by "fairly" when used as a quantifier for the solubility of a chemical?

While doing homework and I found a statement that says a chemical is fairly soluble in water, but I do not understand what this means.

However, I know that when things are soluble in water they tend to dissolve. Is it that fairly soluble in water means that a part of it dissolves, while another part doesn't dissolve?
