binary branching constraint
MORPHOLOGY: a constraint on concatenative
word formation which says that in the process
of word formation only two morphemes can be concatenated at the same time. Hence, the
compound a,i,c either has the structure [[[a] [b]] [c]], or
the structure [[a] [[b] [c]]], but not the ternary structure [[a] [b] [c]].
Circumfixes are problematic with respect to this
SYNTAX: Constraint proposed in
Kayne (1984) which rules out syntactic
structures in which a phrase contains more than two immediate constituents
(i.e. no node in a tree structure may
have more than two branches).
