Abstract: Let *F* be a translation invariant left introverted algebra of bounded continuous real-valued functions on a semigroup *S*. Various equivalent versions of the notion of *F*-left thickness of a subsemigroup *T* are presented, and the relationship between the left amenability of *F* and that of is examined.
