"Principly" is not recognized as a legitimate English word, and therefore, a formal dictionary definition is unavailable. It seems that the word you are referring to may be "principally," which is an adverb derived from the adjective "principal."
"Principally" is commonly used to describe something that is primarily or chiefly the case or the main reason behind a particular action or concept. It indicates the most significant or essential element or aspect within a given context.
The term can also refer to the main purpose, goal, or intention of something. It suggests that an action or decision is driven or guided by a central principle or fundamental value. Furthermore, "principally" can also describe something that is mainly found or located in a specific place or region.
For instance, if someone states, "She is principally responsible for the project's success," it implies that she is primarily accountable and has played a vital role in achieving the project's positive outcome. Similarly, if one mentions that a company is principally engaged in manufacturing, it indicates that manufacturing is their primary area of focus and primary source of revenue.
In short, "principally" indicates the most important or significant factor, purpose, or location within a given context.
