IPA: /dɪˈspjuːtəblɪ/
KK: /dɪˈspjuːtəblɪ/
In a way that can be argued against or questioned; not certain or definite.
The results of the study are disputably valid, as some experts have raised concerns about the methodology.
Disputably is formed from "disputare" (meaning to argue or debate) and the suffix "-ably" (meaning in a manner that can be). The word indicates something that can be argued or debated.
Think of 'arguing' ('disputare') in a way that can be done ('-ably') — that's why disputably means something that can be argued.
