Everyone needs a running list of favorite words. I for one am always trying new favorites. You should keep some on hand in case you get hungry: they're terrific snacks.
At the top of my list at present is presently. It's a lovely word because it means both "currently" and "soon." As in, "Presently I'll be writing about the words that are my favorites presently." Plus one can sorta imagine a bow on top.
Other favorites of the moment:
thrush (the bird, not the illness)
swift (the bird, not the tempo)
What are your favorite words? How do you keep them handy?
