hailstone

the word 'hailstone' is a transparent compound from old english, directly combining 'hagol' (hail) and 'stān' (stone). it is a descriptive term where 'stone' metaphorically emphasizes the hard, pellet-like nature of the frozen precipitation. this compound formation follows a common germanic pattern of creating concrete nouns by joining two elemental words, resulting in a term that literally means a 'stone of hail'. the logic is immediately apparent, comparing the icy pellets to small, hard rocks falling from the sky.

Structure: hail (frozen rain) + stone (hard substance) hail (from old english hagol, meaning frozen rain); stone (from old english stān, meaning a piece of rock or hard mineral substance).
