If it's Visualization, Conditionals are not the matter

The conditionals are said to be extremely difficult for ESL.

However, if you use Visualization, you can understand them more efficiently and effectively.

In addition to from the Zero to 5th Conditionals, there are 8 types, which include "I wish, If only, etc." and the usual constructions describing expected values, such as "I hope that, etc."

(1) Zero Conditional : Real World, Use Simple Present Tense, without Modal Verb, 6 types

(2) 1st Conditional : Real World, Use Simple Present Tense, with Modal Verb, 4 types

・As bases of Present situation in Un-Real World, it represents an Un-able Wish to change the Past.

I wish, if only,I'd rather, etc. are Un-Real World Regret

(7) I wish, if only, etc. : Un-Real World, Use Simple & Perfect Past Tense, 4types

Since it's in Un-Real World, we cannot  use other than the simple or perfect past tense after I wish, etc.

I wish + past simple has same meaning as 2nd Conditional. So, it indicates Un-Real World Regret(Un-able Wish).

I wish + past perfect has mostly the same meaning as 3rd Conditional. So, it indicates Un-Real World Regret of Un-Changeable Past.

But the only difference from the 3rd Conditional is that it cannot express a sense of Relief.

I hope, Probably, I'm sure, etc. are Real World Normal Expectation

(8) I hope, Probably, I'm sure, etc. : Real World, Use Any Tense, Many types

Hope is controversial but my standing place is here;

when Zero, 1st Conditional, and Recommendations are included in Subjunctives, then Hope should be included.

Since it's in Real World, you can use any tense (even in the future tense) after I hope, etc.

I've finished necessary and sufficient explanations.
