IPA: /ˌʌnɪˈskɔːtɪd/
KK: /ʌnɪˈskɔrtɪd/
Describes someone or something that is not accompanied by a person who guides or protects them.
She walked home unescorted after the party ended.
Unescorted → It is formed from "un-" (meaning not) and "escorted" (from Latin "escortare", meaning to lead out or guide). The word "unescorted" means not being led or guided by someone, implying being alone or without company.
Think of 'not' ('un-') being 'led' ('escortare') by someone — that's why unescorted means being alone or without guidance.
