IPA: /nɒn.kənˈtræk.tʃu.əl/
KK: /nɑnˈkɒntræktʃuəl/
This word describes something that is not related to or does not involve a contract.
The agreement was considered noncontractual, meaning it was not legally binding.
Noncontractual → It is formed from "non-" (meaning not) and "contractual" (from Latin "contractus", meaning drawn together or agreed upon). The word "noncontractual" means not related to or not governed by a contract.
Think of 'non-' meaning not, and 'contractual' referring to agreements — so noncontractual means something that is not part of an agreement.
