To whine or complain persistently; to cry or whimper in an irritating manner; to make grey or become grey.
From Middle English 'grislen,' possibly imitative in origin or related to Old English 'gristlian'; has both meanings: turning grey and making complaints.
English has this amazing word that means both 'to complain annoyingly' AND 'to turn grey'—as if our language knew that getting older makes people more inclined to grumble!
