Instrumental Case / तृतीया विभक्ति (tRRitiiya vibhakti): Instrumental Case or तृतीया विभक्ति (tRRitiiya vibhakti) of noun-form represents the instrumental form in a sentence. The answer that comes from the question "by what" or "with what" is the instrument in the sentense. The instrument is with what the subject or कर्ता (kartaa) is doing something. The instrument is independent of the number and gender of the subject or object.

Study the following sentences. These are in instrumental case.
