"Do I go to him?"

[Billbixly]

Really lost here

[Deasun]

hard to see how the "An dt~" generates the question form??

[galaxyrocker]

an in this case is the question particle - it signifies the sentence as a question. It's dt because an here triggers eclipses

[Deasun]

Thanks. I see. its art --> t with the d eclipsing it??

[galaxyrocker]

Yep. <d> is eclipsing <t> here.

《Shall I go to him》 is a wrong alternative here, right ?

[galaxyrocker]

Yes. Shall implies that your asking permission, and that's not covered by this sentence.

[JohanaSchw]

linguists can call An+eclipsed verb the interrogative, ie the question conjugation

[Knocksedan]

Linguists call this an an interrogative particle.

Particles occur before the verb which is otherwise at the start of a sentence, and change the way that sentence is interpreted. An interrogative particle turns a statement into a question, a negative particle negates a statement.

Téim chuige - "I go to him".
An dtéim chuige - "Do I go to him?".
Ni théim chuige - "I don't go to him."
