I like this stolid, resolute word:
(Of a building or structure): square shape and solid appearance. Squarely and solidly: a castle standing four-square on the peninsula. (Of a person or quality): firm and resolute. Firmly and resolutely in support of someone: stand four-square behind integration.
‘What I had always loved was a kind of foursquareness about the utterance, a feeling of living inside a constantly indicative mood.’
