What is the difference between subjunctive and conditional sentences?

Conditional sentences are usually started by 'If' while subjunctive sentences are usually started with a command.

Explanation:

The conditional tense is often used with words, like 'if,' 'would,' 'could,' and 'might. ' this is to express certain conditions that might happen (real or not). Subjunctive is started with a trigger that presents the command (suggestion/order). Its used o express a hypothetical situation that might happen (again real or not)
