Imperatives may also take the form of an invitation when someone is warmly encouraged to do something. As opposed to orders, invitations are expressions of politeness. An example of a LIS sentence expressing an invitation is provided below.
sq
fe
3take2 palm_up
‘Take it!’
In this sentence, the signer is inviting his guest to have a piece of cake. When used to express an invitation, palm_up displays a longer arched relaxed movement. As for non-manual markers, invitations are accompanied by furrowed brows (fe) and squint eyes (sq), plus a head nod.
