IPA: /səˈsɛsɪvnəs/
KK: /səˈsɛsɪvnəs/
The quality or state of happening one after another in a series.
The successiveness of the events made it difficult to keep track of time.
Successiveness → It is formed from "success" (from Latin "successus", meaning outcome or result) and the suffix "-ness" (meaning the state or quality of). The word "successiveness" refers to the state of being successive or occurring in a sequence.
Think of 'success' as an outcome and '-ness' as the quality of that outcome — so 'successiveness' means the quality of outcomes happening in a sequence.
