IPA: /ʌnˈkoʊdɪd/
KK: /ʌnˈkoʊdɪd/
Not having a code or not being organized in a coded system.
The package was sent without a coded label, making it difficult to track.
Uncoded → It is formed from "un-" (meaning not) and "coded" (from the root "code" which comes from Latin "codex", meaning a book or a system of symbols). The word "uncoded" means not encoded or not transformed into a code.
Think of 'not' ('un-') being added to 'coded', which means it hasn't been transformed into a system of symbols.
