IPA: /ɪnˈhoʊldɪŋ/
KK: /ɪnˈhoʊldɪŋ/
A piece of land that is owned by a private individual or group, located within the area of a federal preserve, such as a national park or seashore.
The inholding within the national park made it difficult to expand the protected area.
Inholding is formed from "in-" (meaning within) and "holding" (from the Old English "holdan", meaning to hold or keep). The word refers to the act of holding or keeping something within a certain area or boundary.
Think of 'holding' something 'within' — that's what inholding means.
