'bladder-like' originates from the word 'bladder,' which comes from Old English 'blǣdre,' meaning 'blister' or 'bladder.' The suffix '-like' is used to form adjectives indicating similarity.

'blǣdre' transformed into the Middle English word 'bladdre,' and eventually became the modern English word 'bladder.'

Initially, 'blǣdre' meant 'blister' or 'bladder,' and over time, the meaning has remained largely the same, referring to a sac-like organ or structure.
