Let \( W \) denote the words in the English dictionary. Define the relation \( R \) by \( R=\{(x, y) \in W \times W \) : the words \( x \) and \( y \) have at least one letter in common \}. Then, \( R \) is
(1) not reflexive, symmetric and transitive
(2) reflexive, symmetric and not transitive
(3) reflexive, not symmetric and transitive
(4) reflexive, symmetric and transitive
