A friend of mine had this request:
Alright so I was sitting at this table with a kerosene lamp, and it was a little too bright. Watch out! So I turned a little knobbly thing to lower the flame, and then had the vaguest recollection that there was some verb for this precise action, the dimming of an oil lamp, but a week of pondering and now some searches for "list of lamp actions" have not flushed out any foxes. Can anyone toss me some helps on this one? I think it may be an archaic word that one would find in Charlotte Bronte or Laura Ingalls Wilder, also maybe the kind of word that the Decemberists or Joanna Newsom would bandy about to show they mean nineteenth-century business.
I briefly checked the OED online and some other sources (well, Google) but didn't find anything sufficiently specific. Does anyone know if this word actually exists?
