FAQ
Frequently Asked Questions
Primarily yes, for people abandoning a group. It can be used technically for products/parts ('defected goods'), but 'defective' is far more common in that sense.
They are close synonyms. 'Deserted' often implies abandoning a duty or post (especially military) without permission, while 'defected' strongly implies going over to an opposing side, often for ideological or political reasons.
Rarely. It is neutral in formal reporting, but carries inherent negative connotations of betrayal from the perspective of the abandoned group. The new group may view it positively ('he defected to freedom').
No. The adjectival form meaning 'faulty' is almost always 'defective'. Using 'defected' as an adjective is technical jargon and can sound like an error to many native speakers.
