IPA: /ˌɪntəˈmɪtənsɪ/
KK: /ˌɪntərˈmɪtənsi/
The condition of occurring at irregular intervals; not continuous or steady.

Intermittency → It is formed from "inter-" (meaning between) and "mittere" (meaning to send). The word describes the quality of being sent or occurring between intervals, hence referring to something that happens at irregular intervals.
Think of something that occurs 'between' ('inter-') 'sending' or happening ('mittere') — that's why intermittency means something that happens at irregular intervals.
