many a little makes a mickle

Many a little makes a mickle
C миру по нитке — голому рубашка

[Little and often fills the purse]

A mickle, or as they prefer it in Scotland, a muckle, means 'great or large in size'. Apart from 'many a little (or pickle) makes a mickle' the words only now remain in use in UK place-names, like Muckle Flugga in Shetland (which amply lives up to its translated name of 'large, steep-sided island') and Mickleover in Derbyshire (listed in the Domesday Book as Magna Oufra - 'large village on the hill').
