The differences of meaning that exist between the various forms of the series /hæv, həv, əv, v/ ['have'] are essentially connotative and reflect usage in various types of discourse, which may be described as being increasingly colloquial. That is to say, /hæv/ occurs in a more 'elegant' socio-linguistic context than the form /v/, and the other forms stand somewhere between.
