candid: [17] Originally, candid meant simply ‘white’; its current sense ‘frank’ developed metaphorically via ‘pure’ and ‘unbiased’. English acquired the word, probably through French candide, from Latin candidum, a derivative of the verb candēre ‘be white, glow’ (which is related to English candle, incandescent, and incense).
The derived noun candour is 18th-century in English. Candida, the fungus which causes the disease thrush, got its name from being ‘white’. And in ancient Rome, people who were standing for election wore white togas; they were thus called candidāti, whence English candidate [17]. => candidate, candle, incandescent, incense
