• Economy – People tend to shorten words wherever possible to facilitate faster and easier communication. Phonetic reduction is also an example of economy practiced in language.
• Migration – When language speakers migrate from one area to another, the language they use becomes diluted and borrows from the local language of their current location.
• Flawed learning – An immigrant group can learn a language improperly and then use it in this manner. Their usage will gain popularity in their community and may even overwhelm majority usage, becoming a new standard in itself.
• Contact with other cultures – As already discussed above, coming into contact with other cultures and languages impacts a language. It borrows terms and expressions to supplement their own grammar.
• Reanalysis – Some new words and expressions may be better suited to convey certain events/situations than what was used formerly.
Language keeps changing to reflect societal advances and we shall try to keep up.
