1.4 Catford and the introduction of translation shifts
Catford’s approach to translation equivalence clearly differs from that adopted by Nida since Catford had a preference for a more linguistic-based approach to translation and this approach is based on the linguistic work of Firth and Halliday. His main contribution in the field of translation theory is the introduction of the concepts of types and shifts of translation. Catford proposed very broad types of translation in terms of three criteria:

1. 
   The extent of translation (full translation vs partial translation);
   
   
2. 
   The grammatical rank at which the translation equivalence is established (rank-bound translation vs. unbounded translation);
   
   
3. 
   The levels of language involved in translation (total translation vs. restricted translation).
   

We will refer only to the second type of translation, since this is the one that concerns the concept of equivalence, and we will then move on to analyze the notion of translation shifts, as elaborated by Catford, which are based on the distinction between formal correspondence and textual equivalence. In rank-bound translation an equivalent is sought in the TL for each word, or for each morpheme encountered in the ST. In unbounded translation equivalences are not tied to a particular rank, and we may additionally find equivalences at sentence, clause and other levels. Catford finds five of these ranks or levels in both English and French, while in the Caucasian language Kabardian there are apparently only four.
Thus, a formal correspondence could be said to exist between English, Uzbek and Persian if relations between ranks have approximately the same configuration in three languages, as Catford claims they do.
One of the problems with formal correspondence is that, despite being a useful tool to employ in comparative linguistics, it seems that it is not really relevant in terms of assessing translation equivalence between ST and TT. For this reason we now turn to Catford’s other dimension of correspondence, namely textual equivalence which occurs when any TL text or portion of text is “observed on a particular occasion ... to be the equivalent of a given SL text or portion of text” (ibid.:27). He implements this by a process of commutation, whereby “a competent bilingual informant or translator” is consulted on the translation of various sentences whose ST items are changed in order to observe “what changes if any occur in the TL text as a consequence” (ibid.:28).
As far as translation shifts are concerned, Catford defines them as “departures from formal correspondence in the process of going from the SL to the TL” (ibid.:73). Catford argues that there are two main types of translation shifts, namely level shifts, where the SL item at one linguistic level (e.g. grammar) has a TL equivalent at a different level (e.g. lexis), and category shifts which are divided into four types:

1. 
   Structure-shifts, which involve a grammatical change between the structure of the ST and that of the TT;
   
2. 
   Class-shifts, when a SL item is translated with a TL item which belongs to a different grammatical class, i.e. a verb may be translated with a noun;
   
   
   
3. 
   Unit-shifts, which involve changes in rank;
   
4. 
   Intra-system shifts, which occur when ‘SL and TL possess systems which approximately correspond formally as to their constitution, but when translation involves selection of a non-corresponding term in the TL system’ (ibid.:80). For instance, when the SL singular becomes a TL plural.
   

Catford was very much criticized for his linguistic theory of translation. One of the most scathing criticisms came from Snell-Hornby (1988), who argued that Catford’s definition of textual equivalence is ‘circular’, his theory’s reliance on bilingual informants ‘hopelessly inadequate’, and his example sentences ‘isolated and even absurdly simplistic’ (ibid.:19-20). She considers the concept of equivalence in translation as being an illusion. She asserts that the translation process cannot simply be reduced to a linguistic exercise, as claimed by Catford for instance, since there are also other factors, such as textual, cultural and situational aspects, which should be taken into consideration when translating. In other words, she does not believe that linguistics is the only discipline which enables people to carry out a translation, since translating involves different cultures and different situations at the same time and they do not always match from one language to another.
