'mosquito' originates from Spanish, specifically the word 'mosquito,' where 'mosca' meant 'fly' and the diminutive suffix '-ito' meant 'little.'

'mosquito' changed from the Spanish word 'mosquito' and eventually became the modern English word 'mosquito.'

Initially, it meant 'little fly,' but over time it evolved into its current meaning of 'a small flying insect that bites and can transmit diseases.'
