Morphology

defroster = defrost (transparent) = de + frost + er

The noun is a standard and easily interpretable -er formation from the verb 'defrost', meaning something that defrosts.

Etymology

Defroster comes from de- meaning 'remove', frost meaning 'ice on a surface', and the ending -er meaning 'the thing that does it'. So a defroster is a device that removes ice or frost from a car windshield, a refrigerator, or an airplane's wings.
