insufficient to classify intensifiers, since there exist other words commonly classified as adverbs that never modify verbs but are not intensifiers, e.g. questionably
, they increase the emotional content of an expression. The basic intensifier is very. A versatile word, English permits very to modify adjectives and adverbs, but not verbs. Other intensifiers often express the same intention as very.
Not all intensifiers are the same syntactically since they vary on whether they can be used attributively or predicatively. For example, really and super can be used in both ways:[3]
a. The car is really expensive. - Predicative intensifier
b. the really expensive car - Attributive intensifier
a. Today was super cold. - Predicative intensifier
b. a super cold day - Attributive intensifier
Words such as so can occur only as predicative intensifiers,[3] and others, such as -ass, typically are used only as attributive intensifiers:[4]
a. The car is so expensive. - Predicative intensifier
b. *the so expensive car[note 1] - Attributive intensifier (not grammatical)
a. *Today was cold-ass. - Predicative intensifier (not grammatical)[note 2]
b. a cold-ass day - Attributive intensifier
There is dialectal variation in the "correctness" of certain forms.
Illocutionary force
An intensifier expressly provides an emotional characterization of a lexical item for the benefit of a reader or listener. A speaker or writer's use of the characterization encourages a reader or listener to consider and begin to feel the underlying emotion.[5]
Persuasiveness and credibility
Legal
In general, overuse of intensifiers negatively affects the persuasiveness or credibility of a legal argument.[6] However, if a judge's authoritative written opinion uses a high rate of intensifiers, a lawyer's written appeal of that opinion that also uses a high rate of intensifiers is associated with an increase in favorable outcomes for such appeals. Also, when judges disagree with each other in writing, they tend to use more intensifiers.[citation needed]
Business
A 2010 Stanford Graduate School of Business study[7] found that, in quarterly earnings conference calls, deceptive CEOs use a greater percent quantity of "extreme positive emotions words" than do CEOs telling the truth.[8][9] That finding agrees with the presumption that CEOs attempting to hide poor performance exert themselves more forcefully to persuade their listeners. David F. Larcker and Zakolyukinaz give a list of 115 extreme positive emotions words, including intensifiers: awful, deucedly, emphatically, excellently, fabulously, fantastically, genuinely, gloriously, immensely, incredibly, insanely, keenly, madly, magnificently, marvelously, splendidly, supremely, terrifically, truly, unquestionably, wonderfully, very [good].
A 2013 Forbes Magazine article[10] about counterproductive modes of expression in English specifically discouraged use of really and observed that it provokes doubt and degrades the speaker's credibility: "'Really' – Finder calls this a 'poor attempt to instill candor and truthfulness' that makes clients and coworkers question whether you're really telling the truth."
The narrator. It is easy to tell whether a narrator is narrating because the subject matter interests him or because he wants to evoke interest through his narrative. If the latter is the case, he will exaggerate, use superlatives, etc. Then he usually narrates the worse, because he is not thinking so much about the story as about himself.[11][12]
A quote often attributed to Mark Twain but probably by newspaper editor William Allen White is "Substitute 'damn' every time you're inclined to write 'very'; your editor will delete it and the writing will be just as it should be."[13]
