In this study, we aim to introduce the notion of a parameterized connectedness degree of an L-fuzzy soft set in L-fuzzy (E, K)-soft topological spaces. We first define the notion of a parameterized separatedness degree of L-fuzzy soft sets in L-fuzzy (E, K)-soft topological spaces in terms of closure operators. Then we introduce the notion of a parameterized connectedness degree of L-fuzzy soft sets and generalize some connectedness properties, well known in general topology, to L-fuzzy (E, K)-soft topological spaces.
