IPA: /nɒnɪˈlæstɪk/
KK: /nɑnɪˈlæstɪk/
Describing something that does not stretch or change shape easily.
The material used for the construction was nonelastic, making it rigid and unyielding.
Nonelastic → It is formed from "non-" (meaning not) and "elastic" (from Latin "elasticus", meaning able to return to its original shape). The word "nonelastic" means not able to return to its original shape or form.
Think of 'not' ('non-') being combined with 'able to return to its original shape' ('elastic') — that's why nonelastic means something that cannot return to its original form.
