What does denning mean?
Denning is the present participle of the verb 'to den', meaning to live, shelter, or hole up in a den. Its dominant modern use is in wildlife biology and nature writing, where it describes animals — above all bears — taking up residence in a winter den to sleep through the cold months. Researchers speak of denning sites, denning seasons, and denning behavior when tracking how and where animals settle in. A secondary, more literary sense refers to a person retiring to a private room, study, or hideout, as in 'he spent the evening denning in his library'. The word derives from Old English 'denn', meaning a lair or cave, and carries connotations of seclusion, retreat, and self-protection. Though uncommon in casual conversation, it is precise and evocative wherever animals or people withdraw into sheltered spaces.

Etymology of denning
Denning comes from the verb 'den', which derives from Old English 'denn', meaning a lair, cave, or wild beast's resting place. The noun has Germanic roots and has been part of English since its earliest recorded stages, with the verb form developing later to describe both animal and human retreat into such spaces. The -ing participle follows the standard Modern English pattern and appears most frequently in naturalist and hunting literature from the eighteenth century onward, particularly in accounts of bear hunting and, later, scientific wildlife studies.
