The term 'จนถึงเมื่อ (jon thǔeng mʉ̂a)' is routinely employed in Thai to signal an end point or limit of a time duration, very much like the English words 'until' or 'up until'. It is typically placed between two circumstances or events, with the action in the first clause continuing until the event in the second clause happens. The phrase can be used to express periods or limits of time, actions, or states, and can be used with a wide variety of verbs, adjectives, and phrases.
