IPA: /nɒnˈdɒktrɪnɛə/
KK: /nɑnˈdɑktrəˌnɛr/
Not rigidly adhering to a specific doctrine or set of beliefs; open to different ideas and perspectives.
The committee took a nondoctrinaire approach to solving the problem, considering various viewpoints.
Nondoctrinaire is formed from "non-" (meaning not) and "doctrinaire" (from French, meaning one who adheres strictly to a doctrine). The word describes someone who does not strictly adhere to a particular doctrine or set of beliefs.
Think of 'non-' meaning not, and 'doctrinaire' referring to someone who follows a doctrine. This helps you remember that nondoctrinaire means not strictly following a specific set of beliefs.
