'dryness-resistant' originates from the combination of 'dryness' and 'resistant', where 'dryness' refers to the state of being dry and 'resistant' means able to withstand or oppose something.

'dryness' and 'resistant' were combined in modern English to form the compound adjective 'dryness-resistant'.

Initially, 'dryness' referred to the absence of moisture, and 'resistant' meant able to withstand. Together, they evolved to describe something that can withstand dry conditions.
