Description:

The term 'kile' has the base meaning as a noun of 'back'. Since Common's metaphor of time is that the future is facing you and the past is behind, the word 'kile' often appears in expressions about the past.

As a verb, kile is a transitive skurun verb and means to turn away from someone or something. It takes an ergative subject which is the one who turns and an absolutive object which is the one turned away from. Colloquially, it means to disrespect or betray. This is thought to be a calque from English, although it may also be by analogy to 'pana', 'face', which in Common is used as the opposite of back in referring to the future and also means respect.

The benefactive happat form means to give back or return, and takes an ergative giver, an absolutive thing given and a dative recipient. It is part of the popular expression for turning a question back around on an asker, 'hap kile' or 'hap kile iju (sy)'. The simply 'hap kile' form is popular because it allows the avoidance of second person pronouns while being completely clear.

The derived form 'kilesyn' means the past in general. The shorter derived form 'kiles' means pertaining to the back, or past.
