IPA: /ʌnˈdæmɪdʒd/

Not harmed or affected in a negative way; remaining in good condition.
The package arrived undamaged despite the rough handling during shipping.
Undamaged → It is formed from the prefix "un-" (meaning not) and the root "damaged" (from Old French *damager*, meaning to cause harm or injury). The word "undamaged" means not harmed or injured.
Think of 'not' ('un-') causing 'harm' ('damaged') — that's why undamaged means something that has not been harmed.
