Here's one to redeem my blunder: splendid.
placid and flaccid. Oh, and stupid and putrid.
Being a noun, caryatid doesn't fit the list, but turgid would be a nice addition...
Don't forget caryatid...
Here're some more: pallid, sordid, candid, sapid, rapid, hairdid (I like to combine those words; look in the Urban Dictionary. Wonder if you could use it as an adjective:), squalid, and valid.
but you forgot torrid, and I think that it's a nice word.
