Some examples of connectives are as follows:
| Symbol | Name | Meaning | Example |
|---|---|---|---|
| ¬ | Negation | Negation (NOT) | ¬p (not p) |
| ∧ | Conjunction | Conjunction (AND) | p ∧ q (p and q) |
| ∨ | Disjunction | Disjunction (OR) | p ∨ q (p or q) |
| → or ⇒ | Implication | Implication (IF…THEN) | p → q (if p, then q) |
| ↔ or ⇔ | Equivalence | Equivalence (IF AND ONLY IF) | p ↔ q (p if and only if q) |

| p | q | ¬p | p ∧ q | p ∨ q | p → q | p ⇔ q |
|---|---|---|---|---|---|---|
| True | True | False | True | True | True | True |
| True | False | False | False | True | False | False |
| False | True | True | False | True | True | False |
