φάσμα
Lemma: φάσμα
Translation: spectrum; ghost; specter; phantom; apparition; range (noun)
Etymology: From Ancient Greek φάσμα (phasma) meaning 'apparition, phantom', derived from φαίνω (phaino) 'to show, appear'. The root is related to English 'phantom', 'phase', and 'phenomenon' through the same Indo-European base. The scientific meaning 'spectrum' developed from the idea of something that appears or is revealed, particularly light made visible through a prism. This dual meaning of both supernatural apparition and scientific phenomenon makes it uniquely memorable - both ghosts and light spectra are things that 'appear' to us.
Mnemonics
- Think 'phantom' - both words share the same Greek root and similar meaning
- Remember 'phase' - spectra show different phases of light

Explanation: φάση means 'phase' or 'stage' while φάσμα means 'spectrum' or 'ghost' - they share the same root but have different applications
Notes: Both come from the same Greek root φαίνω (to appear) but φάση is more about temporal stages while φάσμα is about ranges or apparitions
Mnemonic: φάσμα has the extra 'μα' - think 'phantom' which also has more letters and means ghost like φάσμα
