How do you ask questions in Slovak?
I know "kto, čo, ked', gedje, prečo a ako", but how do you ask complex questions? Examples:

Do/ does/ did (you/ it)...?
May (I)...?
Can (I)...?
Could (you)...?
If...?
Is/ are there...?
Is it/ Are they...?

Also are there any grammatical changes I should be aware of when asking a question?

Answer

Do/ does/ did (you/ it)...?   Hovoríš anglicky? (Do you speak English?) Verb goes first. In most cases you don`t need to change anything, just use intonation.

May (I)...? Môžem /Smiem....?
Can (I)...? Môžem...? (the same as previous)
Could (you)...? Mohol by si...?
If...?     Here I am not sure what question you want to ask...
Is/ are there...?  Je tu/Sú tu...?
Is it/ Are they...? Je to/Sú to...?

kto, čo, ked', kde je (pronounced "gde je"), prečo a ako, kedy (when)

Hope it helps
