Are Lunc and Luna the same?

Could you please clarify for me? Are Lunc and Luna interchangeable terms, or do they refer to distinct concepts within the realm of cryptocurrency? I've been hearing both names used, and I'm curious as to whether they refer to the same thing or possess separate meanings. If they are not the same, could you possibly elaborate on their respective characteristics and functions within the crypto ecosystem? Your insights would be greatly appreciated as I seek to expand my understanding of this fascinating field.
