# 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)).
