collocations
Have a look at the excellent research being done on collocations by, among others, Cobuild, Oxford University Press and Longman dictionaries. They are each compiling a corpus of language from radio, television, the press and literature and then analysing and extrapolating data for word frequencies, collocations, usage etc.
When looking at words which 'go together' like "capable of", the frequency of 'capable' and 'of' appearing next to each other is so high that any other combination is virtually non-existent - and wrong.
