Conjunction

In semantics and syntax, conjunction is the combination of two sentences or clauses with 'and'.

Comments
In propositional logic, the conjunction of two formulas Phi and Psi, written Phi & Psi, is true if both Phi and Psi are true, otherwise it is false. The truth table of conjunction is therefore as follows:

Phi   Psi	     Phi & Psi 1	   1	   	 1     1      0	  	 0     0	    1	   	 0     0	    0	   	 0

Polysemy
Conjunction is also used in the sense 'coordinator or subordinator' (see conjunction (i.e. connective)).
