in or near or toward a center or according to a central role or function
"The theater is centrally located"
In a central manner or situation; at, to, through or from the centre.
"The city's main square is located centrally within the historic district."
In plain English: Centrally means located right in the middle of something, away from the edges.
"The hotel is centrally located, making it easy to reach all major tourist attractions on foot."
Usage: Use "centrally" when describing location relative to a core area rather than as an adjective modifying a noun like "central." Avoid confusing it with "centered," which implies being focused on a specific point or theme.
Centrally comes from combining the word central with the suffix -ly. It entered English as a straightforward formation to describe something located at or near the center.
