IPA: /dɪsˈpɛn.sə.bɪl.ɪ.ti/
KK: /dɪsˈpɛn.sə.bɪl.ɪ.ti/
The quality or condition of being able to be replaced or not necessary.
The dispensability of certain tasks allows the team to focus on more important projects.
Dispensability is formed from "dis-" (meaning apart) and "pensare" (meaning to weigh or consider), along with the suffix "-ability" (meaning the quality of being). The term refers to the quality of being able to be set apart or not essential.
Think of 'weighing' ('pensare') options and being able to set something 'apart' ('dis-') — that's why dispensability means something that can be considered non-essential.
