As a noun, 'keul' has a very wide range of possible meanings. It can be an act of turning, an act of change, a turn in a game, a season of the year, or a bounded period of time marked by some commonality.

This can be disambigueated in various ways if needed - for example, 'ny keul na hulaz' is a seaon of the year. If modified with 'cajre', 'exact', though, it pinpoints a time of change, so 'ny cajre keul na hulaz' would be the turn of the year, or a way of saying New Years, and 'ny cajre keul na keul' would be the turn of a season, a solstice or equinox.

The derived form 'keulca', based on the causative form of the verb, is the word for 'modifier' in Common linguistics.

The derived from 'rokéul' can refer to a retreat, flip or reversal.

Modifier:

The modifier form rokéulys means 'flipped' or 'reversed'.
