The particles were not evenly spread, causing unreliable outcomes.


formal

Not consistent or identical in form, composition, or quality; varying or irregular.

The fabric had a non-uniform texture, with some areas thicker than others.

The fabric's thickness varied, making it irregular in quality.

The data collected from the sensors was non-uniform, which complicated the analysis.

Pro Tip

Use in technical writing

When describing data, materials, or processes, 'non-uniform' is preferred over 'uneven' for precision, especially in scientific or engineering contexts.

Gold Rule

Avoid redundancy

Do not use 'non-uniform' with words like 'different' or 'varied'—it already implies inconsistency.

Word Origin

From Latin 'non' (not) + 'uniformis' (uniform), where 'uniformis' combines 'unus' (one) + 'forma' (form).

Usage Notes

Commonly used in academic, technical, and professional writing to describe lack of uniformity. Avoid using it in informal contexts where simpler terms like 'uneven' or 'mixed' would suffice.
