What is an "earthworm"?
An earthworm is a terrestrial annelid worm belonging to the family Lumbricidae. It has a long, cylindrical body divided into segments. Earthworms are essential for soil health and fertility as they tunnel through the soil, improving its structure and nutrient content. They feed on organic matter, breaking it down and facilitating decomposition. Earthworms also play a vital role in soil aeration and water infiltration, benefiting plant growth. Due to their ecological significance, earthworms are considered valuable indicators of soil health and are widely studied by scientists and ecologists.

What is the origin of the term "earthworm" and how is it used?
"Earthworm" is a slang term that dates back to at least the 18th–19th centuries, using the literal worm as a metaphor for weakness, lowliness, or insignificance because earthworms are small, soft, and live underground. The term conveys contempt, emphasizing a lack of power, courage, or status. It has appeared in literature, speeches, and informal speech to belittle someone, and is generally derogatory, used to insult or demean, though it is mild compared with harsher epithets.
