For a given vocabulary L and infinite cardinals µ ≤ κ, Lκµ is the infinitary logic with κ variables, conjunctions and disjunctions over sets of formulas of size.

Let τ be a vocabulary, i.e., a set of function symbols, relation symbols and constant symbols. In the logic L∞,ω(τ) we build formulas using the symbols.
