The word 'mond' does not appear to be an English word. It might be a typo or a misinterpretation of the English word "mind." If that is the case, "mind" refers to the element of a person that enables them to think, feel, and be aware of the world. It encompasses thoughts, consciousness, perception, reasoning, and emotions.
The word "mind" comes from Old English "gemynd," which means "memory, remembrance." It has Proto-Germanic roots in *ga-minþi, which conveys a sense of memory or thought.
