What does platy mean?
Platy is an informal North American shortening of platypus, the unusual mammal native to eastern Australia and Tasmania. It refers to the same animal known for its ducklike bill, broad webbed feet, and unusual habit of laying eggs. Although platy is an established and recognizable word, it remains casual compared with the full name platypus, which is preferred in scientific, educational, and formal writing. The shortened form is especially common in conversation about animals encountered at sanctuaries, wildlife parks, or in the wild, and it can sound affectionate as well as familiar. The name ultimately comes from Greek platypous, meaning broad-footed, an apt description of the animal's distinctive limbs. Platy is therefore useful in informal English when the speaker wants a familiar, compact name without the slightly formal or technical effect of platypus.

Where does platy come from?
Platy is an English clipping of the longer word platypus. Platypus comes from Greek platypous, a compound of platys, meaning broad or flat, and pous, meaning foot; it therefore literally means broad-footed. English words such as plateau and platform are also related through the ancient root for a broad, flat, or level surface.
