Although I agree that this is an uncommon word(a very specific literary device), isn't it still mentioned in high school English classes? I remember learning about it in the 10th grade.

Here's an example of it in literature. This is the first verse of Poe's "Bells"




Hear the sledges with the bells-
Silver bells!
What a world of merriment their melody foretells!
How they tinkle, tinkle, tinkle,
In the icy air of night!
While the stars that oversprinkle
All the heavens, seem to twinkle
With a crystalline delight;
Keeping time, time, time,
In a sort of Runic rhyme,
To the tintinnabulation that so musically wells
From the bells, bells, bells, bells,
Bells, bells, bells-
From the jingling and the tinkling of the bells.

It's the thing where a word sounds exactly like the thing it's describing like "bang," "boom," etc.
