Unibrow vs. Monobrow — What's the Difference?

Difference Between Unibrow and Monobrow


Key Differences

Unibrow and monobrow both describe the appearance of a single, continuous eyebrow due to a lack of separation over the nose bridge. However, "unibrow" is more commonly used in American English, while "monobrow" tends to be more popular in British English.
The word "unibrow" originates from combining "uni-" meaning "one" with "brow," indicating one eyebrow. Monobrow similarly combines "mono-" meaning "single" with "brow." Both terms aim to capture the idea of a singular eyebrow, though they originate from different roots.
In terms of spelling, "unibrow" contains seven letters and "monobrow" contains eight. Both are compound words that blend their respective prefixes with "brow." Despite these slight variations, the words are essentially synonymous in meaning.
Unibrow and monobrow are both nouns and can be used in similar grammatical constructions. You could say, "He has a unibrow," or "He has a monobrow," and both would be understood the same way.
In popular culture, both "unibrow" and "monobrow" are widely understood, but you're more likely to hear "unibrow" in an American movie and "monobrow" in a British series. Regardless, they convey the same image: a single eyebrow rather than two separate ones.
