The average credit card balance in Australia is around $3,200, and the average balance which is accruing interest is a little over $2,000. More than a third of Aussies pay back their balance before the expiry of the interest free period and therefore pay very little for the use of the card (Source: The Age).
Caryn /ca-ryn/ [2 sylls.] as a name for girls is of Greek derivation, and the name Caryn means pure. Caryn is an alternate form of Catherine (Greek): from katharos. Caryn is also a variation of Karen (Danish, Greek). Caryn is also used as a derivative of Katherine (Greek).
This is likely cognate to the popular Welsh girls' name Carys. The name is also that of an island in the Inner Hebrides island group, Scotland; Cara Island lying just off the southern tip of the Isle of Gigha. In Turkey the word Kara means dark, which may or may not be related to the Gaelic Ciara of the same meaning.
