For example, take the following two simple propositions:

- Kato is a dog.
- Kato is a mammal.

But, since every proposition, whether simple or compound, has a truth value,
the conjunction of two propositions will be true in only one case: when *both component are true*.

In ordinary language there are many different words that serve the logical function of conjunction: ‘and’, ‘but’, ‘yet’, ‘also’,
‘still’, ‘both’, ‘however’, ‘moreover’, ‘nevertheless’, ‘additionally’, etc. While these words have distinct meanings in ordinary
language, in Propositional Logic they all perform the same logical function: *connecting two simple propositions into a compound
proposition*.
