means The practice of reading a person's character or future by studying the lines, shapes, and mounts of their palm.

from From Middle English 'palmestry,' built from 'palm' (the hand, via Old French and Latin 'palma') plus a suffix echoing words like 'archery' or 'heraldry' — naming it a craft or skilled practice. It's a cousin of 'chiromancy,' the more learned Greek-rooted term (kheir, 'hand,' + manteia, 'divination') that scholars once preferred while 'palmistry' stayed the everyday, fairground word for the same old trick of finding destiny in your own skin.
