etymology of 'mosquito'
If 'mosquito' is derived from 'mosca', why does the gender change?
1 Answer
c.1583, from Sp. mosquito "little gnat," dim. of mosca "fly," from L. musca "fly," from PIE base *mu-, perhaps imitative of the sound of humming insects. Colloquial form skeeter is attested from 1839.
I guess it changes because it ends in "o"
