Etymology: Ampicillin is a compound built from two chemical names, not from a single ancient root. Its first half, "am", is a clipping of "amino-", the name for the group of atoms containing nitrogen that chemists identified in amino acids and related compounds. That "amino-" element traces back through the word "amine", which combines the "ammon" of ancient Egyptian and Greek sources (the god Amun, whose temple region produced a salt later named after him) with the Latin-derived suffix "-ine," used in chemistry to mark a chemical substance. The second half comes from penicillin, named after the mould "Penicillium," itself a Latin-style coinage built on the Latin "penicillus," a painter's brush. The mould's brush-like spore branches gave the genus its name, and the "-in" ending was added to form the name of the antibiotic substance. Ampicillin was then made by chemists who joined the two elements, combining a nitrogen-containing chemical prefix with the penicillin name to describe a modified penicillin.
