'batch-stored' originates from the combination of 'batch' and 'store', where 'batch' meant 'a group of items' and 'store' meant 'to keep or accumulate'.

'batch' changed from the Old English word 'bæcce' meaning 'a group of items' and 'store' from the Old French 'estorer', eventually becoming the modern English word 'store'.

Initially, 'batch' meant 'a group of items', and 'store' meant 'to keep or accumulate', evolving into the current meaning of 'stored in groups'.
