Recontextualisation is a process that extracts text, signs or meaning from its original context (decontextualisation) in order to introduce it into another context. Since the meaning of texts and signs depend on their context, recontextualisation implies a change of meaning, and often of the communicative purpose too. The Linguist Per Linell defines recontextualisation as:

the dynamic transfer-and-transformation of something from one discourse/text-in-context ... to another.

Linell distinguishes between recontextualisation at three diffent levels:

• intratextual: recontextualisation within the same text, discourse or conversation. Intratextual recontextualisation plays an important part in most discourse in so far as it refers to what have been said before, or anticipates what is to be said. In conversation, for instance, the one part usually infuses what the other part just - or earlier - has said in a new context thus adding new meaning to it. Such turns of decontextualisation and recontextualisation combined with metadiscursive regulation are crucial for the continual unfolding of texts, discourses and conversations. .
• intertextual: recontextualisation relations to specific texts, discourses or conversations. It is an important aspect of texts that they explicitly or implicitly fetch elements from other texts. The importance of this becomes clear when it is realised the meaning of a word is based on its meaning in other contexts; it could be an encyclopaedia, but more often its meaning stems from contexts in which it is used. See: intertextuality
  Intertextuality
  Intertextuality is the shaping of texts' meanings by other texts. It can include an author’s borrowing and transformation of a prior text or to a reader’s referencing of one text in reading another. The term “intertextuality” has, itself, been borrowed and transformed many times since it was coined...
  
  
• interdiscursive: recontextualisation between types of discourse, such as genres. In Fairclough, chains of genres is closely connected to interdiscursive recontextualisation. Chains of genres denotes how genres depend on each others discursive material, e.g. the relation between interviews, transcription of interviews and the analysis of interviews. However, interdiscursive recontextualisation is also abundant between large interdiscursive entities or formation and is part of society's discursive workshare. An example is the import of results from statistic theory into social science with the purpose of testing quantitative analyses. See: interdiscourse
  Interdiscourse
  Interdiscourse is the implicit or explicit relations that a discourse has to other discourses. Interdiscursivity is the aspect of a discourse that relates it to other discourses. Norman Fairclough prefers the concept "orders of discourse". Interdiscursivity is often mostly an analytic concept, e.g....
  
  

Though recontextualisation often is used within linguistics, it also has interdisciplinary applications. Particularly, in Basil Bernstein

Basil Bernstein

Basil Bernstein was a British sociologist and linguist, known for his work in the sociology of education.-Biography:...

's concept of the pedagogic device that consists of three fields: the fields of production, recontextualisation and reproduction. The field of reproduction is the field of schooling institutions. The field of production is the field, where knowledge is produced (often universities). The field of recontextualisation mediates between these two fields. The recontextualisation field "is composed of two sub-fields; namely, the official recontextualising field (ORF) and the pedagogic recontextualising field (PRF). The ORF consists of 'specialized departments and sub-agencies of the State and local educational authorities'. The PRF consists of university departments of education, their research as well as specialised educational media
