From a 'Guide to Lex & Yacc' (no link, sorry):

3.  YACC
3.1  Theory

"Terms that appear on the left-hand side (lhs) of a production, such
as E(expression) are nonterminals.  Terms such as id(identifier) are
terminals (tokens returned by lex) and only appear on the right-hand
side (rhs) of a production."
