Modelling Change
Aitchison’s PIDC model documents the timeline of how language changes. Halliday believes that language changes as a result of the needs and requirements of the users of the language.

Jean Aitchison
- One of the most influential and important linguists for language change is Jean Aitchison.
- Aitchison’s PIDC model documents the timeline of how language changes...

Aitchison’s PIDC model
- Potential – there is the gap or potential for change.
- Implementation – the change occurs.
- Diffusion – the change spreads.
- Codification – the change is made official (e.g. being added to the dictionary).

Halliday
- Halliday believes that language changes as a result of the needs and requirements of the users of the language.
- This can work in two ways...

Halliday’s functional theory
- Lexical gaps – there is a gap in the lexicon for something which needs describing.
- For example, ‘laptop’.

Halliday’s functional theory cont.
- Function shifts – where a word exists, but we need a different word class.
- For example, ‘Google’ as:
- A noun (‘I found it on Google’).
- A verb (‘I’ll Google it’).
- An adjective (‘A Google search’).
Other Theories
Hockett’s theory accounts for errors. Substratum theory explains how changes can be made as a result of interactions with other languages and variations of English.

Hockett’s ‘random fluctuation’ theory
- Hockett’s theory accounts for errors.
- He says that when someone makes an error (a ‘random fluctuation’ in the standard), these errors can be standardised and recognised as somewhat synonymous.
- For example, iPhones famously autocorrect ‘fuck’ and ‘fucking’ to ‘duck’ and ‘ducking’, sparking social media attention and memes.

Substratum theory
- Substratum theory explains how changes can be made as a result of interactions with other languages and variations of English.
- For example, British English saw an increase in the use of ‘like’ as an intensifier as a result of American English use of it on TV shows like FRIENDS.

Substratum changes
- The most common explanation for substratum changes include:
- The media (the above example).
- Invasion (the French invasion of 1066).
- Immigration (as in MLE).
- Through travel and exploration (as in the birth of America).
Crystal & Aitchison
Crystal describes language changing as being like the tide. Aitchison created 3 models to describe attitudes towards language change.

David Crystal’s tide metaphor
- Crystal describes language changing as being like the tide – new things get washed up on shore and the tide takes other things away.
- Sometimes things make it onto the beach permanently, others only momentarily.

David Crystal’s tide metaphor cont.
- In addition, there are never two tides exactly the same – some tides will only impact certain parts of the beach.
- The metaphor explains that all change is different, lasts differing amounts of time and affects different groups of people.

Aitchison’s prescriptivist attitudes
- Aitchison created 3 models to describe attitudes towards language change.
- However it is important to note that Aitchison does not believe that language change is any of these things – quite the opposite – she is a descriptivist.
- These are attitudes which prescriptivists have.

Damp spoon syndrome
- Damp spoon syndrome:
- This stems from the distasteful act of leaving a damp spoon in a bowl of sugar.
- This implies that people are lazy and disrespectful of language.
- For example, the growing trend of ‘g-dropping’.

Infectious disease assumption
- Infectious disease assumption:
- This is all about the idea that changes are like germs which spread and infect the language.
- For example, text language is often described as infecting our language.
- This is all about the idea that changes are like germs which spread and infect the language.

Crumbling castle view
- Crumbling castle view:
- This is all about the idea of that English was at some point at a ‘golden age’ and is now in a state of disrepair.
