IPA: /ˌʌn.kɒn.trəˈdɪk.tɪd/
KK: /ʌnˌkɒntrəˈdɪktɪd/
Not denied or challenged; accepted as true without any disagreement.
The witness's testimony was uncontradicted, making it a strong piece of evidence in the trial.
Uncontradicted → It is formed from "un-" (meaning not), "contra-" (meaning against), and "dicere" (meaning to say). The word describes something that has not been said against or disputed.
Think of 'not' ('un-') having anything 'said against' ('contra-' and 'dicere') — that's why uncontradicted means something that has no opposition.
