5 letters clue is in that place if other words OK then it is T?O?N
T comes from 11 letters "hindering" O comes from 5 letters "freight"
N comes from 7 letters defining position in series taken to be "ordinal"
Totally stuck
Thanks
answer i thought for hindering was obstructive,that gave the 't' for freight I got cargo hence the 'o' and for clu efining position in series - ordinal which gave 'n'the 'c' for cargo and 'o' for ordinal came from cl book-keeping which I got accountancy.
thaks for trying al,but still at a loss !.
whole clue is 'in that place' other clues forming the letters are book-keeping (accountancy)freight (cargo) ennui (boredom the 'm' in boredom comes from figure - number)hindering (obstructive) defining position in series (ordinal)
beginning to suspect a compilation error but again thanks for trying.
