Chapter 1

Of all the word types in English, none is stranger than the interjection. Words such as ‘oops’, ‘boo’ and ‘whoa’ function like no other type of word in the language, and as such are grouped together based on their shared ability to express spontaneous reactions or feelings. In this short two-chapter reader on interjections, we answer in Chapter 1 the question of whether it’s OK to use words such as these in formal settings like academic essays and explore in Chapter 2 their grammar rules.  

What are the major word types?

As in all languages around the world, English words can be categorised into various types through the analysis of shared patterns of form, function and distribution. Before studying interjections as a unified class of words, first study the academic examples below of each of the more common word types:


Adjectives: absolute, basic, competitive, distinct, effective, fundamental, ideal, permanent

Adverbs: accurately, consequently, furthermore, however, inevitably, similarly, successfully

Conjunctions: although, and, as, because, even though, but, that, whether, while

Determiners: a, an, any, every, few, some, the, that, this, those

Nouns: achievement, criticism, experiment, hypothesis, knowledge, majority, percentage

Prepositions: above, below, between, in, over, under

Pronouns: anyone, everything, it, that, this, which, whoever, whom

Verbs: achieve, benefit, conduct, demonstrate, examine, facilitate, highlight, investigate


What makes interjections unique?

So what do words such as ‘bravo’, ‘hurray’ and ‘phew’ have in common that groups them together under the classification of interjection? Firstly, unlike all other word types, interjections relate to the expression of feelings rather than to the expression of concepts or ideas. These feelings can be subclassified in three ways:

What additionally makes interjections unique is that:


  1. they can form complete sentences alone (‘Shh!’ and ‘Wow!’ are grammatical sentences according to most grammarians)
  2. they are dependent upon the context in which they are used (it would be impossible to know what ‘shh’ or ‘wow’ refer to without knowing their surrounding expressions)
  3. they cannot often be modified or inflected (‘shh’ and ‘wow’ will always be spelled the same)
  4. they do not provide grammatical function within a sentence (their function is semantic rather than grammatical, adding meaning to an expression).

Can I use interjections in formal writing?

While interjections might be interesting and fun, they’re not always useful. Academic language is famously objective, scientific, unambiguous and direct, and interjections such as ‘boo’ or ‘eek’ simply are not. Emotive words are inappropriate in academic discourse and would lower your marks in an assignment if included. For these reasons, students should remember that interjections are one word type that should never used in academic essays. Instead, you can call upon these words when chatting informally with your friends (or even to your university lecturer) and perhaps creatively as part of character dialogue within a novel or script. 


Which interjections are most common in English?

To help students use interjections, we’ve identified and listed the most common examples below, dividing them into the three previously mentioned categories to assist with meaning. To use these words correctly however, we recommend that you research their specific meanings online with a dictionary such as Cambridge or Oxford and practise using them in authentic situations:



Cognitive Interjections

alas, bingo, bravo, crikey, duh, eh, eureka, gah, haha, hallelujah, hmm, oh dear, phew, right-o, shoot, thanks, uh-huh, uh-oh, zing



Emotive Interjections

aww, bah, brr, dang, eww, grr, gosh, holy cow, humph, hooray, jeepers, jeez, oh my, oh well, oops, ugh, whoa, whoopee, wow, yahoo, yeah, yikes, yippee, yuck



Volitive Interjections

ahem, boo, cheers, congrats, cheerio, please, psst, shh, shoo, yo
