'sac-like' originates from the word 'sac,' which comes from the Latin word 'saccus,' meaning 'bag.' The suffix '-like' is used in English to denote resemblance.

'saccus' transformed into the Old French word 'sac,' and eventually became the modern English word 'sac.' The suffix '-like' was added to form 'sac-like.'

Initially, 'sac' meant 'bag,' and the term 'sac-like' evolved to describe anything resembling a bag or pouch.
