Google, and you will find people continually using the
word "object" to refer to both atomic objects, and to an
object that returns references to some of its interior
objects.

David Hopwood's usage is new, unusual, non standard, and
not English.

The standard and long established usage is that an
aggregate object is an object that exposes references to
some of its interior objects, and an atomic object is an
object does not - but both of them are objects.

Good practice is to avoid exposing references to
interior objects unless genuinely needed - aggregated
objects are complex, and one should avoid unnecessary
complexity.
