means Complete, entire, with nothing missing or removed.

from From Old English 'hāl,' meaning sound, healthy, uninjured — the same root that gives us 'hale' (as in hale and hearty) and 'heal.' To be whole was first to be unbroken in body, only later unbroken in count. That sneaky 'w' at the front is a latecomer, a spelling fashion that crept in around the 15th century and never left, even though nobody pronounces it. It shares deep ancestry with 'holy' too — both circling the idea of something untouched, intact, set apart.
