This code attempts to make basic syntax trees in the Xcode console. It is designed to roughly follow basic X-Bar theory.

Overview of X-Bar theory

– All phrases have a head (X), a bar level (X′), and a phrasal level (XP)
XP -> X’ -> X

– Specifier: sister of X′, daughter of XP
XP -> Spec X’

– Adjunct: sister and daughter of X′
X’ -> Adjunct X’

– Complement: sister of X, daughter of X′
X’ -> X Complement
