"Palier" in terms of a "landing" on a staircase is just one dictionary definition but there are others, this one being common in scuba diving and mountaineering contexts. "Palier" is also used more generally to describe a stage being reached, a level. I do'nt know if you are familiar with the GDT, the granddictionnaire.com, but it's a good first reference to eliminate a number of possibilities and often gives a few prompts for further research is one's general knowledge falls short. I've learnt to scuba dive in France and so "palier" is first and foremost a "stop" for me anyway. Reading further trhough the dictionary definitions would probably have got this oen for you. ;-) |
