When you examine the data, you
may obtain a roster of facts or phenomena you have observed.
You should not leave them like that. Instead, you have
to sort them and put them in categories so that they become
easily retrievable information. The process of establishing
categories is part of categorization. For example, after
examining the cohesion in a piece, you have marked all
the cohesive ties existing in the text. You then need
to figure out which particular cohesive device is manifested
in a given cohesive tie.
Before we set out to do the exercise below, it may
be necessary to remind you of the definition of cohesive
tie and the major types of cohesive device. Whenever
the interpretation of an element in a text depends on
another element in the text, a cohesive tie is thought
to have been established between the two elements. The
major types of cohesive device include: reference, substitution,
ellipsis, conjunction, and lexical cohesion (Halliday
and Hasan 1976).
