The meaning of “Hollow”

It’s interesting how many West Virginians (and Appalachians) know “hollow” (pronounced: holler) as a place where people live/a road/neighborhood/community but yet the actual definition of the word couldn’t be more different:
hol·low
- Having a cavity, gap, or space within: a hollow wall.
- Deeply indented or concave; sunken
- Without substance or character: a hollow person.
- Devoid of truth or validity
- Having a reverberating, sepulchral sound: hollow footsteps.
- A cavity, gap, or space: a hollow behind a wall.
- An indented or concave surface or area.
- A void; an emptiness: a hollow in one’s life.
- A small valley between mountains (this rings the most true for me)
For the purposes of this project, I chose “Hollow” because it symbolizes home to many while also symbolizing emptiness (population loss).
However, I find it quite intriguing how a word that many use to describe their beloved and secure home also signifies a place that is void of “substance.”
