Here let us try to make some more simple sentences. Let's try to ask simple questions using the word 'when' and try to use simple sentences to answer them. The word 'kadaa (कदा) ' gives the meaning when.
Let's say you would like to ask when does Alex go? That would be,
'Alexaha kadaa gachchati? (अलेक्षः कदा गच्छति )?'
Let us say, Alex goes at 7 o'clock. That would be,
'Alexaha saptavaadane gachchati (अलेक्षः सप्तवादने गच्छति )'

Try to make as many sentences as you would like using these new words that you have learned. Play with the words and I am sure you will find it fun.
