“Under One’s Belt” – The Core Definition
The idiom “under one’s belt” means to have achieved, experienced, or completed something successfully, especially something that adds to your skills or knowledge.

| Literal Meaning | Figurative Meaning |
| Having food or drink literally under your belt (after eating) | Having achievements, experiences, or skills gained and secured |
Originally, this phrase referred to consumption—food or drink that you had literally put under your belt. Over time, it took on a metaphorical sense of absorbing or “taking in” experiences and knowledge.
Historical Background and Origin of “Under One’s Belt”
The idiom dates back to the early 19th century, when “under the belt” referred to food or alcohol consumed—something physically “inside” you. The phrase gradually shifted to a metaphorical sense in the late 1800s, meaning something you’ve gained or achieved.
The Early Use
In old English taverns and sailor communities, saying someone had “a few drinks under their belt” meant they had consumed alcohol. Over time, this idea of “having something inside” extended to experiences or accomplishments.
The Shift in Meaning
By the late 19th century, the idiom started appearing in books and newspapers describing experience or achievements, such as:
“He’s got two years of training under his belt now.”
The Oxford English Dictionary and Merriam-Webster both cite examples of this figurative use emerging around the 1880s to 1890s.
The idea stuck because it paints a vivid image: once you’ve done something and “put it under your belt,” it becomes part of who you are—a permanent addition to your skill set or experience.
