'water-sensitive' originates from the combination of 'water' and 'sensitive', where 'water' refers to the liquid essential for life and 'sensitive' means easily affected by external factors.

'Water-sensitive' is a modern English term formed by combining 'water' and 'sensitive', reflecting the increasing awareness of materials and environments that react to water.

Initially, it meant 'easily affected by water', and this meaning has largely remained the same in modern usage.
