The word atom derives from the Greek, ατoμos, which means indivisible or uncuttable.

Explanation:

Some of the early Greek philosophers (circa 6th/5th century BC) proposed that the atom was the smallest unit of matter. This probably derived more from philosophical notions than from experiment, and today we know that atoms are composed of protons, neutrons, and electrons.
