'bag-like' originates from the English word 'bag' combined with the suffix '-like', where 'bag' meant 'a flexible container' and '-like' meant 'resembling or similar to'.

'bag' changed from the Old Norse word 'baggi' and eventually became the modern English word 'bag'.

Initially, 'bag' meant 'a flexible container', and this meaning has largely remained the same in modern usage.
