Full stops intimidate young people when used in social media communication as they are interpreted as a sign of anger, according to linguistic experts.

Teenagers and those in their early twenties, classified as Generation Z, have grown up with smartphones which they use to send short messages without full stops.

And a study from Binghamton University in New York suggested that people who finish messages with full stops are perceived as insincere.

Linguistic experts are now investigating why teens interpret a correctly-punctuated text as a signal of irritation.
