Context 19:50 Nov 26, 2011
Whilst understanding the confidentiality problem, which we all have from time to time and as a basic rule of professional integrity, is there no chance of a little more context? All you are likely to get is a series of the standard likely possibilities. Instalments reads as a good choice but how can anyone tell without more context... pretty please??? Looks a little like a guess-the-missing-word game as is! ;-)
With no more context, I'd feel safest with Rebecca's suggestion of using 'tranche'. |
