One kind of modification that appears in simplified registers seems intended to make the language more ‘correct’ or ‘standard’ than the normal usage of adult-adult informal conversation. Modifications of this kind that represent ‘upgrading’ processes are more common in language teacher registers and ‘talking-up’ kinds of FT than in BT or talking-down’ FT […] but examples can be found in almost any kind of simplified register.
