100 Mostly Small But Expressive Interjections By Mark Nichol

They often seem disreputable, like sullen idlers loitering in a public thoroughfare, but they actually do a lot of hard work and are usually persnickety about the tasks to which they are put. They are interjections — one class of them, anyway: those lacking etymological origins but packed with meaning.

But how do you know how to distinguish similar ones — or spell them, for that matter? Here’s an incomplete inventory of interjections (not including variations of actual words such as yeah for yes or onomatopoeic echoes of externally produced sounds like boom):

Ack communicates disgust or dismissal.

Ah can denote positive emotions like relief or delight (generally, pronounced with a long a).

Aha signals triumph or surprise, or perhaps derision.

Ahem is employed to gain attention.

Argh, often drawn out with additional h’s, is all about frustration.

Aw can be dismissive or indicative of disappointment, or, when drawn out, expressive of sympathy or adoration.

Aye denotes agreement.

Bah is dismissive.

Use it to indicate comprehension or acknowledgment (or, with a question mark, a request for verification), to preface direct address (“Oh, sir!”), as a sign of approximation or example (“Oh, about three days”), or to express emotion or serves as a response to a pain or pleasure. (Ooh is a variant useful for the last two purposes.)
