Father:
 
The world father has a range of meanings such as, a male parent of a child, an important figure in history responsible for the creation of something; "the father of abstract art." The founding father. It can be a verb: to father someone. In Christianity the father refers to God.  Father is the name given to a priest. It can also be used to show respect:  the oldest members of a society, the fathers. (Elders, leaders)
 
The word "father" can be traced back to the Latin word 'pater'.

There was a process called "the great consonant shift" which meant that related languages began to change and letters such as 

"p" began to be pronounced as "f" or "v",

"t" began to be pronounced as "d"

 

This explains why the Latin word "pater" translates so similarly into various European languages as:

vater - German

faeder - Old English
padre - Italian & Spanish

Middle English: Father

Widespread phonetic shift in Middle English that turned -der to -ther in many words

Attitudes to Language Change

Prescriptivists: Believe that language has to be accurate, right or wrong.

Descriptivists: Notice Language Change objectively.

Three metaphors used by prescriptivists to talk about language change are; the ‘damp spoon’ syndrome, the ‘crumbling castle’ view and the ‘infectious disease’ assumption.

• The ‘crumbling castle’ refers to how the English Language was once a magnificent castle but over the years it has crumbled away. Jean Aitchinson disagrees with this stating that as a language is constantly changing there could be no single point at which it was magnificent. “No year,” she said, “can be found when language achieved some peak of perfection.”

• The ‘damp spoon’ suggests that language change is due to laziness. Aitchinson disagrees again saying that, “The only truly lazy speech is drunken speech, where alcohol affects coordination, and English is not getting like drunken speech.”

• The ‘infectious disease’ suggests that ‘bad English’ is like a disease which is spread. Aitchinson says that this is technically correct but it is no disease.  Douglas Bush says that, “…the disease metaphor falls down… people pick up changes because they want to.”

There is an argument which suggests that the changes in our language are similar to the changes in our fashion. However a Guardian article by David Shariatmadari suggests that this is not the case. He explores the debated which language change creates, “Fashions come and go too, but it's hard to think of clothes that excite the same hot-under-the-collar debates.” He mentions the bad grammar award nominations which suggest that many still take a prescriptivist attitude to language.
