== shika == leave of absence, furlough
Left radical is 'shell/money' (貝), which in this case means 'valuable item'.
Right radical is 'easy/divination' (易), which acts phonetically to express
'great volume'. This character originally meant a large, valuable reward
bestowed by a ruler. Henshall suggests as a mnemonic:
'Bestowal is easy money.'
