IPA: /nɒnˈnoʊbəl/
KK: /nɑːnˈnoʊbəl/
Describing someone or something that does not have noble qualities or status; lacking in honor or high moral principles.
The nonnoble actions of the character revealed his true nature.
Nonnoble → It is formed from "non-" (meaning not) and "noble" (from Latin "nobilis", meaning well-known or high-born). The word "nonnoble" means not noble or lacking nobility.
Think of 'non-' meaning not, and 'noble' referring to high status — so nonnoble describes someone who does not have that high status.
