Translation:If I went home without you, would you be angry?
Hello, I know the "-us" ending is used in Eo for conditional, but here, i wrote "If I go home without you, shall you be angry?", and it was not accepted.
Why do you have to use the past tenses in English to express conditional?
In French (my mother language) it seems ok to use both "Si j'allais [past tense] à la maison sans toi, serais-tu [conditional tense] fâché?" or "Si je vais [kind of present continuous] à la maison sans toi, seras-tu [future] fâché?"
Thanks for all the help you will provide me :)
In Esperanto, and in many languages there are many different verb tenses based off the time the action is taken place. This may be familiar in English as we have past tense and present tense. However, in Esperanto and many other languages there are many more verb forms.
The two you are specifically referencing is called "Future tense" (will be angry...) which is basically saying that, that action will happen. In Esperanto, verbs that have -os ending will have this tense.
The other tense you reference is called "Conditional Tense" this tense confused me at first with Future. Basically, Conditional Mood is a concept that is unreal, conditional, proposed, or imagined. Verbs with this tense end with "-us" In English this translates roughly to "would be angry". The sentence says "Would you be angry?" The person asking isn't saying they will be angry 100%. They are angry if it is a possible event.
A way to not confuse this with Future Tense is to remember that rarely, Conditional Tense can be used to say a possible thing that could've happened in the past. For an example, "Se Zamenhof lernus la ĉina lingvo, tiam Esperanto diferencus." -> "If Zamenhof has learned Chinese, then Esperanto would be different." The verb, "lerni", isn't saying he DID learn, it says that in an alternate scenario where he did learn it, then Esperanto would be different.
If you are still confused, I recommend reading the "Tips and Notes" on lessons. These are a major help in understanding. Specifically, go back to the "Past and Future Tense'" lesson, scroll down and read. Do the same for the "Conditional Tense" lesson. Note: this is only on computer, if you are not able to access these notes, tell me and I can provide them!
I hope this helps! :)
