ABSTRACT
The titles Dr, Mr, Mrs, Messrs are always abbreviated when used with names. (Ms is not strictly an abbreviation but a blend of Mrs and Miss.) Other standard abbreviations are a.m. and p.m., BC and AD, Jr. (e.g. James Smith Jr.), and those for large organisations (e.g. CBI=Confederation of British Industry or TUC=Trades Union Congress). In formal writing, titles indicating high rank are given in full (President, Prime Minister, Reverend) but they may be abbreviated or clipped in informal writing especially when used with initials or first names (e.g. Professor Smith, Prof. J.A.Smith).
