multilevel

Imagine a tall building: it does not stop at one floor. It rises through several levels, and each one connects to the next. That is the basic idea behind "multilevel." It describes something that has more than one level, layer, or stage instead of being all on one plane or in one simple part. You might park your car in a multilevel garage downtown or walk through a multilevel store with different departments on different floors.

The word is also used for systems and plans. A company may have a multilevel management structure, with workers, supervisors, and executives at different levels. A study may look at a problem in a multilevel way by considering the individual, the group, and the wider system together. You may also see it written as "multi-level," and both forms mean the same thing.

"Multilevel" describes anything made up of more than one level, layer, or stage. The levels may be physical, like the floors of a building, or they may be part of a system, plan, or pattern. In the most literal sense, the word is often used for places such as parking garages, homes, stores, or office buildings that are built on several floors or split levels.

The word is also common in business, education, science, and technology. A company can have a multilevel structure, with authority divided across several ranks. In research, a multilevel model studies data that is grouped into levels, such as students within classes and classes within schools. In computing, a multilevel system may give different users different levels of access or control. In writing or film, a multilevel story can work on more than one level at once, offering both a surface story and deeper meaning.

Sometimes the word simply means "with several floors," and sometimes it means "organized in several connected stages or ranks." In both cases, the core idea is the same: the thing is not single-layered or one-dimensional. It is built across levels that relate to one another and help form the whole.
