IPA: /ˌdɪs.kənˈtɪn.ju.əs.li/
KK: /dɪsˈkɒntɪnuəsli/
In a way that is not continuous; occurring at separate intervals or points rather than in a steady flow.
The train runs discontinuously, with long breaks between arrivals.
Discontinuously → It is formed from "dis-" (meaning apart) and "continuus" (from Latin, meaning continuous). The word describes something that occurs in separate parts or intervals, rather than in a continuous manner.
Think of something happening 'apart' ('dis-') from a 'continuous' flow — that's why discontinuously means occurring in separate intervals.
