A polite reply to such a request might be:
Sizsiz toy olar?
What, a party without you?
Wlbwttw dwvwt edwcwyik.
Of course, we’ll invite you.
Sizin yeriniz ba]da olacaq.
Your place will be at the head [meaning, at the head of the table].
If the host does not intend to invite someone for a particular reason, he will give an
excuse to avoid hurting the feelings of the person seeking an invitation:
Demwk olar ki, he[ kwsi [a`\rm\r\q. Ancaq 3-4 nwfwr yax\n qohumlar\m\z olacaq.
We are hardly inviting anyone. We will have only 3-4 close relatives.
