Usage notes
In American English, to moonlight is simply to work at secondary employment;[Mish, Drederick C. (ed.). 1995. Merriam-Webster's Collegiate Dictionary.'' 10th ed. Springfield, MA: Merriam-Webster.] in British English, it used to imply working secretly (i.e., not paying tax on the extra money earned), but more recent editions of some UK dictionaries no longer mention a difference to the US usage.[Treffry, Diana (ed.). 1999.
