Noun to pronoun conversion characteristically occurs with nouns denoting a unique profession which has social status. More nouns of this kind are masterteacher, dûmnyparson, notarisnotary, kastleininn keeper. Such professions are relatively unique; a village tends to have one teacher, one doctor, and so on. More specifically, if you are in a class, there is only one teacher. If you are in a church, there is only one parson, and so on. Nouns denoting family relations, referred to as kinship terms, may also be used in this way, as is shown by the example below:

More nouns allowing this are heitfather, pakegranddad, beppegrandmother, omkeuncle, muoike or tanteaunt. Professional nouns and family nouns can also be used in the vocative. The nouns, when used as pronouns of address, seem to have lost their character as R-expressions:

However, they cannot function as lexical anaphors, whereas ordinary pronouns can:

Furthermore, it seems that they cannot be bound by pronouns (whereas ordinarily pronouns can be bound by pronouns), for the subject pronoun cannot be construed as referring to the same person as pakegrandfather:

In this respect, they are similar to epithets like dy gekthat fool. However, epithets cannot be bound, whereas nouns of address can (as we saw):

So, the two instances of pakegranddad can refer to the same person, whereas the two instances of dy gekthat fool cannot.
