Exercise 5.1

In the examples below from the exercise, the point of interruption is shown by ||, the editing expression (if there is one) is underlined, and the point of restart. The phases of original expression, edit and repair are marked by [ ] and are in blue, red, and green respectively.

a.  [ first I need to find out ] [ || um ] [ I need to get an engine ]
b.  [ Well, I think it's ] [ || you know ] [ I think this has gone beyond, as it were, Al Qaeda as a specific network ]
c.  [ in order to be ] [ || whereas ] [ to actually get into something that most people would recognise as being Rome ]
d.  [ a lot more good for you than European ] [ || ] [ continental European youth hostels ]

The well-formedness rule for repairs states that the error, or the complete sentence constituent of which it would have been part, must be able to form a grammatically complete coordinated structure(e.g. with and) when joined with the repair. On this basis, the repairs are all well-formed, because a coordination of the original expression and the repair would be grammatical (assuming we assume that find out in a. is part of a complete constituent with some object, which we will represent here with something (and similarly for other examples):

a.  first I need to find out something and I need to get an engine.
b.  Well, I think it's done something and I think this has gone beyond, as it were, Al Qaeda as a specific network
c.  in order to be somewhere to actually get into something that most people would recognise as being Rome
d.  a lot more good for you than European and continental European youth hostels

d. is a revision rather than a repair, as the expression a lot more good for you than European youth hostels would have been incomplete rather than incorrect.
