'sack-like' originates from the English word 'sack,' which comes from the Old English 'sacc,' derived from the Latin 'saccus,' meaning 'bag.' The suffix '-like' is used to form adjectives indicating resemblance.

'saccus' transformed into the Old English word 'sacc,' and eventually became the modern English word 'sack.' The suffix '-like' has been used in English since the Middle Ages to form adjectives.

Initially, 'sack' meant 'a large bag,' and the meaning has evolved to include the adjective form 'sack-like,' indicating resemblance to a sack.
