LIS has a construction called Imperative and Declarative (IaD) (SYNTAX 1.3.9) expressing the possibility of an event, which differs in form, but not in meaning, from a conditional clause. The Declarative and Imperative is so called as it is a bi-clausal construction composed of an imperative clause (SYNTAX 1.3) followed by a declarative clause (SYNTAX 1.1). It is marked by the following non-manual markers obligatorily spreading over the imperative clause: squint eyes (sq), raised eyebrows (re), and chin down (cd).
