 p1 ^ ...^ pm => q1 V ... V qn.
or, equivalently,

 ~p1 V ... V ~pn V q1 V ... V qn,
where pi and qi are atoms.

The operators ~, ^, V, => are connectives, where ~ stands for negation, ^ for conjunction, V for disjunction and => for implication.

2.   (grammar)   A part of a sentence (or programming language statement) that does not constitute a full sentence, e.g. an adjectival clause in human language or a WHERE clause in a SQL statement.
