Agglomerate is a kind of rock. It forms when bits from a volcano — stones, ash, lumps of lava — get so hot that they melt and stick into one rough mass. It is not one smooth stone; you can often still see the pieces, baked together like a badly made cake. This is a geology word, so you will meet it in science class or on a volcano walk, not in everyday chat. Though actually, the same word is also a verb and an adjective meaning “clump together into a mass” — powder in a factory can agglomerate — and that older idea is why the rock has this name: loose volcanic bits were wound into one ball.

- The bustle of a croud is not ill-adapted to the pencil: but the management of it requires great artifice. The whole must be massed together, and considered as one body. ¶ I mean not to have the whole body so agglomerated, as to consist of no detached groups: but to have these groups […] appear to belong to one whole, by the artifice of composition, and the effect of light.
- 1820, William Hazlitt, “Explanations—Conversation on the Drama with Coleridge” in Dramatic Essays London: Scott, 1895, p. 197, His [Jean Racine’s] tragedies are not poetry, are not passion, are not imagination: they are a parcel of set speeches, of epigrammatic conceits, of declamatory phrases, without any of the glow, and glancing rapidity, and principle of fusion in the mind of the poet, to agglomerate them into grandeur, or blend them into harmony.
