To scale up a mountain to ascend, to climb up. I am curious how the word 'scale' become associated with climbing up, when it means, more or less, of scales on fish, or of weighing device. Anyone's thoughts on this? Thanks a real lot guys!
"to climb by or as by a ladder," late 14c., from scale (n.) "a ladder," from Latin scala "ladder, flight of stairs," from *scansla, from stem of scandere "to climb" (see scan (v.)). Related: Scaled; scaling.
Many thanks guys. Would scaling down be readily understandable as descending, as scaling up for ascending? None of the dictionary mentions scaling down as descent, instead it's sizing down or some sort of adjustments.
