"Poles like to address themselves with nicknames. For the first nickname men get „-ek“ attached to their names. Tomasz becomes „Tomek“ and Piotr becomes „Piorek“. Women’s names have „-ka“ attached. Emilia becomes „Emilka“, „Anna“ becomes „Anka“. But almost every Polish first name has several diminutives. The rule is: the more you like a person the further you can diminish the diminutives of his name. „Tomek“ turns into „Tomuś” and „Piotrek” into „Piotruś”. Anna, the most common Polish name for women, offers particularly wide scope for affectionate diminutives: Ania, Ancia, Anka, Aneczka, Anulka, Anula, Anucha, Anuszka and so on. Be sure – there will be enough new names for every new year of your marriage!"
