1. Text is limited compared to spoken language, so therefore people have been created features to imitate the impressions of what happens inside a spoken conversation. For example;
Smilies 🙂 are paralinguistic features that imitate facial features and facial features imply emotion, 🙂 🙁
Asterisk *facepalm* (paralinguistic feature) is used to substitute the movement of the character you are talking to, a set of stage directions.
IM WRITING IN CAPITAL LETTERS BECAUSE IM ANGRY!!!!!!! People use capital letters to indicate shouting or anger, this is a more eye catching piece of text on the page because it stands out from the rest of the page. (paralinguistic feature)
2. Spoken language has a variety of creative features. For example;
Dialect (speaking attributes) whats up fam, so in this one phrase we have “fam” which is short for family and is usually said to people that the person cares about as family is signified as love and care, so he treats this person as family so why not give them the name of bruv which is a synonym inside the context of this dialect.
Accent, (speaking attribute) people talk in accents in different locations and these can be accents for the media or to fit into their local group. These accents could be used to individualize certain social groups and show them from the crowd.
3. Spoken language is beginning to be influenced by text communication;
People are starting to use lol (initilism) inside spoken language, this is because lol is a very standardized initilism and means laugh out loud, people have been using this to signify that the comment they said was funny or they thought a comment was funny but was not so funny that they would laugh about it, so it could be said as an indication of humour.
This is the same concept for YOLO, however people use YOLO (initilism) as a scape goat to do whatever they want really.
