What does sesquipedalian mean?

Sesquipedalian is a word used to describe language that contains long, polysyllabic words or a style that seems overly wordy. It is often used to comment on writing or speech that feels elaborate, dense, or difficult to follow.

In everyday use, the term can be neutral, descriptive, or mildly critical depending on the context.

Literal meaning and origin

The word comes from Latin roots and is traditionally explained as meaning “a foot and a half long.” It was used to describe something unusually long, and later came to refer to long words and long-winded language.

Historically, the term is associated with criticism of verbosity in writing. Over time, it became a useful label for language that sounds impressive but may not be especially clear.

How is sesquipedalian used?

Writers and speakers may use sesquipedalian to describe a person, a sentence, or a style of communication. It often suggests a preference for long words rather than simple, direct language.

In some settings, that can sound scholarly or playful. In others, it can imply that the message is harder to understand than it needs to be.

Pronunciation

The pronunciation is commonly given as /ˌsɛs.kwɪ.pɪˈdeɪ.li.ən/.

Breaking it into parts can help: ses-kwih-pih-DAY-lee-uhn.
