What does nesting mean?
Nesting denotes the activity of building or occupying a nest, most commonly in reference to birds preparing a site in which to lay eggs, incubate them, and raise their young. The word can also name the nest itself or a place where animals shelter, and by extension it describes one object or structure enclosed within another. In computing, nesting refers to subordinate arrangements such as folders placed inside other folders or information organized at multiple levels. The term is common in expressions including nesting site, nesting season, and nesting instinct. Nesting behaviour is especially associated with seasonal reproduction and may involve elaborate selection of a sheltered location, preparation of the nest, and repeated care of the developing young. More broadly, the word conveys the ideas of shelter, enclosure, and orderly containment.

Where does nesting come from?
Nesting developed in Middle English from the Old English nest, with the suffix -ing. The word nest is inherited from Proto-Germanic and ultimately relates to a wider Indo-European family of words for a nest or resting place, including Latin nīdus. Nestle was likewise formed within the Germanic family from the same basic idea of a sheltered place.
