My suggestion Caveat Emptor was just a shot in the dark as I had no access to the crossword and the information provided by those asking for help was lacking in required detail. So, please, give all the necessary F??????G information
I agree with Trev, the only one which really matches "observe carefully" is nota bene, but as you say, we need to know the number of letters. And you, Jimbo, need to be back in the colluvies vitiorum to try and reach 200!
You think that I need to be back in the colluvies vitiorum? I cannot believe it! What have I done to deserve this? Parting is such sweet sorrow, but if it has to be, so be it.
Sorry I didn't get back with thanks last night guys only my husband told me to go to bed. nota bene it is, only I haven't tried a word forum before and didn't know the rules.
