foursquare

Foursquare means solidly planted or firmly established, suggesting stability and honesty.

A foursquare stance is steady and balanced; a foursquare position on an issue is unwavering and direct.

The word can describe physical squareness—something with four equal sides—but more often conveys moral straightforwardness: She stood foursquare behind her decision.

As an adverb, it means squarely or directly: He faced the challenge foursquare. (Capitalized Foursquare is a location-based social network or a Pentecostal denomination.)
