I’m not an expert in english grammar, but here’s what I remember.
will is called a “modal auxiliary verb.”
will + infinitive = future
e.g. I will finish my homework after Batman is over.
would + infinitive = present conditional
e.g. If Batman weren’t on TV, I would finish my homework.
would + have + past participle = past conditional
e.g. If Batman had not been on TV, I would have finished my homework.
A verb is in the subjunctive mood when it expresses a condition which is not factual. It is often in a sentence starting with if, or following a verb such as “wish”.
If Batman were not on TV, I would do my homework.
“If Batman were”: the verb “were” is in the subjunective mood.
I wish that Batman were on television.
again, “were” is in the subjunctive mood.
The subjunctive form is the same as the indicative form except for the verb “to be”, and the third person singular present tense.
