2.1 Combining. A result of morphological reduction or shortening a name can produce a combining form that is used to form new names. It may be useful to divide the various uses of this form into two or three types of combination. 1) The first piece to be combined becomes a prefix that attaches to many different names. 2) The second piece becomes a suffix that attaches to a) many different names or b) their reduced forms.
It is possible that analogy is playing a part in making the parts of a name detachable. The example with Brooklyn may have occurred in two steps, with the first caused by an interaction between the given name form Brook and the toponym. The fact that there was a feminine ending -ine or -in on some names may then have been the motivation creating this as a new spelling -lyn on girls names. The ending -inda may be a variation from the feminine name Linda where the r could on phonological grounds disolve the initial l in that name. This could then be an instance of blending.
