IPA: /nɒnˈjuːnɪfɔːmɪti/
KK: /nɑnˈjunɪˌfɔrˌmɪti/
The state or quality of being different in form, size, or texture; not uniform or consistent throughout.
The nonuniformity of the fabric made it difficult to sew the pieces together evenly.
Nonuniformity → It is formed from "non-" (meaning not) and "uniformis" (from Latin, meaning having one form or shape) and "-ity" (a suffix used to form nouns indicating a state or condition). The word "nonuniformity" means the state of not being uniform or consistent in form or character.
Think of 'not' ('non-') being applied to something that is 'one form' ('uniformis') — this helps you remember that nonuniformity refers to a lack of consistency in form.
