Interrupting

INTERRUPTING
An interrupting phrase is a word group (a statement, question, or exclamation) that interrupts the flow of a sentence and is usually set off by commas, dashes, or parentheses. An interrupting phrase is also called an interrupter, an insertion, or a mid-sentence interruption.
The use of interrupting words, phrases, and clauses, says Robert A. Harris, "confers a natural, spoken, informal feel to a sentence" (Writing with Clarity and Style, 2003).

Interrupting Phrases and the Conversational Style

(154) Even in Lewis Thomas's sentence below, the interruption has the air of speech: 'I bring up these shoals of numbers and their repeated cycles, when reduced to single digits, not out of vanity (although I admit to some self-indulgence) but rather the opposite: to disclose that I cannot be a mathematician.' (167) The purpose of interruptions is usually to add information... ."

Interrupting Phrases as Attention Getting Device

It creates the sense that the writer could not wait until the next sentence to make an announcement relevant to the current idea. The emphasis of the interruption is most profound when dashes are used and when the interruption consists of an entire sentence ... ."
