"Would you like this cookie?"
Translation:Velisne hoc crustulum?
Yes, you can put the verb at the end (most common) or at another place. When it's not accepted, click the report button.
with the -ne, it's more common to have it at the beginning of the sentence. I've found than an author used -ne 90% of the time with the first word, usually a verb, so it's a good practice to take this habit.
The -ne has to be on the word it puts the interrogation (so, usually the verb).
"These cookies" is "Haec crustula".
