What does ergate mean?
An ergate is a worker ant: one of the wingless, typically sterile females that carry out the day-to-day labor of an ant colony. While queens devote themselves to reproduction and males exist chiefly to mate, ergates do nearly everything else — foraging for food, building and defending the nest, tending the young, and caring for their queen. The term comes from the Greek word for 'workman' and belongs primarily to the vocabulary of entomologists and myrmecology literature rather than everyday conversation, where 'worker ant' serves the same purpose. Within the field it is genuinely useful because ant societies can contain multiple physically distinct worker forms, sometimes called minor and major castes, and 'ergate' offers a precise, single-word way to refer to them collectively. For readers interested in social insects, it is a small but elegant piece of scientific terminology.
nounA worker ant — a sterile or non-reproductive female ant that performs the labor of the colony, such as foraging, nest maintenance, and brood care.
- A non-reproductive female worker ant that performs labor for the colony.
"The foraging trail was crowded with ergates carrying seeds back to the nest."
"The ergates swarmed over the fallen fig, dismantling it piece by piece."
"In many ant species, ergates are subdivided into minor and major castes with distinct body sizes."
Regular English plural, formed by adding -s.
"Thousands of ergates emerged from the mound after the rain."
Every ant you've ever seen scurrying across a picnic blanket was almost certainly an ergate — the queen rarely leaves the nest her whole life.

Etymology of ergate
The word ergate derives from the Greek 'ergatēs', meaning 'workman' or 'laborer', which itself comes from 'ergon', meaning 'work'. It entered English as part of the scientific vocabulary of entomology, alongside related coinages built on the same root, such as 'ergatoid' (worker-like). Its cousins from the same Greek stem include 'energy', 'synergy', and 'liturgy', all of which preserve the underlying sense of activity or work.
How ergate is actually used
Ergate is a technical term used mainly in myrmecology (the study of ants) and formal entomological writing; in everyday speech, 'worker ant' is far more common. The plural is simply 'ergates'.
