'drought-prone' originates from the combination of 'drought,' which comes from Old English 'drūgath,' meaning 'dryness,' and 'prone,' from Latin 'pronus,' meaning 'leaning forward.'

'drought' changed from Old English 'drūgath' to the modern English word 'drought,' and 'prone' evolved from Latin 'pronus' to the modern English 'prone.'

Initially, 'drought' meant 'dryness,' and 'prone' meant 'leaning forward,' but together they evolved to describe areas likely to experience dry conditions.
