FAQ
Frequently Asked Questions
Historically, yes. Modern 'pencil lead' is made of graphite, which was historically called plumbago or 'black lead.' Today, 'graphite' is the standard term in industry and science.
The name derives from the Latin 'plumbum' (lead), either because the plant's blue flowers were thought to resemble lead colour, or because it was once believed to be a cure for lead poisoning.
The standard pronunciation is /plʌmˈbeɪɡoʊ/ in American English and /plʌmˈbeɪɡəʊ/ in British English. The stress is on the second syllable: plum-BAY-go.
Yes, for the plant (countable noun): 'plumbagos'. For the mineral (uncountable noun), it is generally not pluralised, though 'plumbagos' can refer to multiple types or specimens of the ore.

Learning
Memory Aids
Mnemonic
Think 'plumber' – plumbers once used lead pipes; 'plumbago' was mistaken for lead ('plumbum'). The 'ago' makes it a 'lead-like' substance. It helps to remember two leads: the metal and the pencil 'lead' (which is actually graphite/plumbago).
Conceptual Metaphor
MATERIAL FOR FUNCTION (Graphite/plumbago is used for marking, thus stands for the act of drawing or writing). RESEMBLANCE (Plant named for its lead-coloured seeds/o resemblance to the mineral).
