Morphology

CFL = compact + fluorescent + lamp (semi-transparent) = C + F + L

CFL is an initialism for 'compact fluorescent lamp'; the meaning is directly derived from those component words. [Postprocessing: changed transparency from 'transparent' to 'semi-transparent' for abbreviation]

Etymology

CFL is short for compact fluorescent lamp, where compact means 'small' and fluorescent means 'to glow' like bright signs. So a CFL is a small, energy-saving light that uses a fluorescent tube to make light and is used instead of traditional bulbs.
