What is meant by delinquency? When will I be termed delinquent?

It means you can't afford to make any payments on your dues for several months. Is there anything else you want to know? You can ask here anytime :)

When you're unable to make payments on your credit cards or loans for several months, then you're termed delinquent. In simple words, delinquency means past due accounts.

It means having past due accounts. Why are you asking? If you have delinquent accounts, then pay them off as soon as possible to avoid debt collection calls.
