To increase or grow quickly in intensity, seriousness, or level. It is often used for conflicts, prices, or problems that get worse over time.
From *escalator*, which came from Latin *scala* 'ladder' and French *escalade* 'an assault with ladders'. The verb *escalate* originally meant 'to climb' and later took on the sense of things 'going up' in intensity.
Esclate is literally 'to go up the ladder', which is why we use it when arguments climb from mild to explosive. The word’s link to escalators makes it oddly modern—our language for rising tension comes from a moving staircase. It suggests that once escalation starts, it can feel automatic unless someone hits the stop button.
