We will also include a detailed table of ugly English words, their meanings, and why they feel uncomfortable.

What Are Ugly Words — And Why Do These Ugly Words Sound Harsh?

The term ugly words refers to words that many English speakers feel sound unpleasant. Linguists say these reactions come from:

• sound combinations that feel “wet,” “heavy,” or “scratchy”

• consonants like “gr,” “sl,” “ph,” “cr”

• associations with unpleasant things

• long, uneven syllable patterns

Even without meaning, some combinations feel uncomfortable — for example:
phlegm, slurp, curdle, gurgle, mucus.

These appear often in lists of 100 ugliest words in the English language, not because they are bad, but because of how they sound in everyday speech.
