Sounds like a rare exotic metallic element.
But no - all I found was this:
Subramaniam, Subramanyam or Subramanian (Tamil:
சுப்பிரமணியம்; Telugu: సుబ్రహ్మణ్యం) is a male given
name in South India and Sri Lanka. Due the South Indian
tradition of using patronymic surnames it may also be a
surname for males and females. The etymology of the name
is unknown; however, a common translation is "dear to
Brahmins", or "of good deeds." An alternative proposed
translation is derived from merging two common
Sanskrit/Tamil words supri-ya (सु), meaning "good" or
"dear," and mani-ya, meaning jewel; the name translates
loosely as "worthy jewel". Subramaniam is one of the
many names of the Hindu god Murugan.

This concludes today's lesson in etymology.

All good stuff.
