panoply

Panoply comes from the Greek word panoplia, which referred to the full suit of armor worn by "hoplites," heavily armed infantry soldiers of ancient Greece. "Panoplia" is a blend of the prefix pan-, meaning "all," and hopla, meaning "arms" or "armor." (As you may have guessed already, "hopla" is also an ancestor of "hoplite.") "Panoply" entered the English language in the 17th century, and since then it has developed other senses which extend both the "armor" and the "full set" aspects of its original use.
