Definitions and Uses
An interjection is an
exclamation that
expresses
feeling or emotion.
They have no grammatical value
but we use them quite often,
usually more in speaking than in
writing.
When interjections are inserted into
a sentence, they have no
grammatical connection to the
sentence.
Interjections like er and um
are also known as hesitation
devices.
They are extremely common in
English.
People use them when they don’t
know what to say, or to indicate that
they are thinking about what to say.
Interjections are set off by
either one or two commas or
an exclamation point. Generally,
use commas to set off interjections
expressing mild emotion, a
exclamation
points to set off those expressing
strong
emotions.
