Which speech pattern could be caused by someone thinking of a specific word that they may not know in English?

One speech pattern that could be caused by someone thinking of a specific word they may not know in English is circumlocution. Circumlocution refers to the act of using excessive words or roundabout expressions to describe something when the exact word for it is not readily available. This often occurs when a person is searching for a specific vocabulary item or trying to explain a concept they are not fully familiar with in their second language.

A speech pattern that could be caused by someone thinking of a specific word they may not know in English is known as "hesitation" or "pausing." When someone is searching for a word or trying to recall a specific term, they may pause, repeat sounds or syllables, use filler words (like "um" or "uh"), or provide alternative descriptions while they gather their thoughts. Hesitation in speech is a common phenomenon, especially when a speaker is unsure of a particular word or phrase in their repertoire.
