Questions & Answers about Se vi mensogas al mi, mi tuj rimarkas tion.
Why are both verbs in -as?
Because -as is the present tense, and in Esperanto the present tense is also used for general truths, habits, and repeated situations.
So this sentence does not have to mean only one specific moment right now. It can mean:
If/whenever you lie to me, I notice it immediately.
That is why mensogas and rimarkas both sound natural here.
Why isn’t it Se vi mensogus al mi, mi tuj rimarkus tion?
Because -us is for something hypothetical, less real, or contrary to fact.
- Se vi mensogas al mi, mi tuj rimarkas tion = a real or general condition
- Se vi mensogus al mi, mi tuj rimarkus tion = If you were to lie to me, I would notice it immediately
So se does not automatically require -us. You use -us only when the meaning is hypothetical.
Why is it mensogas al mi and not mensogas min?
Because the person you lie to is introduced with al.
In Esperanto, mensogi works like lie, and the listener is not a direct object here. So:
- mensogi al iu = to lie to someone
That is why al mi is correct, and min would be wrong in this sentence.
