Assemble and cluster both bring things together, with a difference in order. Assemble is to fit parts together into a whole, or to gather people in one place, in an ordered, purposeful way. Cluster is to gather into a tight, dense bunch, held only by nearness, with no order. Assemble brings things together in order; cluster crowds them close.
Both draw things together, but assemble does it in order and cluster just crowds them close. Assemble, from Latin ad- 'to' and simul 'together', fits parts into a whole or gathers people for a purpose. Cluster gathers things into a tight bunch where each stays itself, held only by how near they crowd. A crew assembles the parts into a machine; grapes cluster on a stem. One puts things together in order; the other packs them close with no plan.
assemble
To assemble is to bring parts together in order so they form one built thing — assemble a shelf, assemble an engine — or to bring people together in one place, as a crowd assembles or a committee assembles. From the Latin ad- 'to' and simul 'together'. Assembling is more deliberate than to gather: the parts are fitted in a set order, each in its place, until a working whole stands. What you gather is loose; what you assemble is put together on purpose.
cluster
A cluster is a group of things packed closely together — a cluster of grapes, of stars, of houses — and to cluster is for them to gather into such a tight bunch. From the Old English clyster, an old word for a bunch or branch of things growing together, a bunch of grapes being the classic image. What defines a cluster is not a boundary but density: the members crowd near one another, closer than to anything outside. The word stretches from the spatial (stars cluster) to the temporal (a cluster of events) and the technical (a cluster of data points).

| Meaning | fit parts together in order; gather | gather into a tight, dense bunch |

| Noun | assembly | a cluster / clustering |
| Example | Assemble the parts. | The houses cluster. |
Ask whether things come together in order or just crowd close. Assemble fits parts or people together for a purpose — boards locking into a cabinet. Cluster packs separate things near one another with no plan — grapes crowding on a stem. If things are brought together in order, that is assemble; if they merely crowd close and dense, that is cluster.

Assemble is deliberate and ordered — parts fitted into a whole or people gathered for a purpose; cluster is just a dense crowding by nearness, with no order or plan. Assembled parts make a working whole; clustered things merely sit close. One arranges; the other crowds.
