The Sanskrit word 'dīrgha' (दीर्घ) means 'long', 'extended', 'prolonged', or 'uninterrupted'. It specifically refers to length or duration - something that is long without break. While related to continuity, 'dīrgha' emphasizes length rather than just continuous repetition. It's not related to deer (that would be 'mṛga' or 'haya') nor does it mean 'good' (that's 'utkara' or 'sadguṇa').
