I wonder what is the origin of the idiom "foursquare behind". I read it in language reference but I can not find its origin. Please, help me!!!
Hi, as a Brit & mentor, but not a teacher, I hope the following reference, from websters Online Dictionary helps:
1. Characterized by firm and unwavering conviction; "a foursquare refusal to yield".
It also has a link to appropriate historical references:
Date "foursquare" was first used in popular English literature: sometime before 1886. (references)
