A western scholar must de-europeanize himself, and, in view of the most universal use of English, an Englishman must de-Anglicize himself as well. - John Rupert Firth

The various structures of sentences in any given language, comprising for example at least two nominal pieces and a verbal piece must be collated, and such categories as voice, mood, affirmative, negative, tense, aspect, gender, number, person and case, if found applicable and valid in descriptive statement, are to be abstracted from, and referred back to the sentence as a whole.

The study of such words as work, labour, trade, employ, occupy, play, leisure, time, hours, means, self-respect, in all their derivatives and compounds in sociologically significant contexts during the last twenty years would be quite enlightening. So would the study of words particularly associated with the dress, occupations, and ambitions of women, or the language of advertising, especially of quackery, entertainments, food, drink, or of political movements and propaganda.

Collocations are actual words in habitual company. A word in a usual collocation stares you in the face just as it is. Colligations cannot be of words as such. Colligations of grammatical categories related in a grammatical structure do not necessarily follow word divisions or even sub-divisions of words.
