CELEX has no specific attribute-value tag for Proper Nouns as a separate category, but has a proper noun subclassification tag set distinguishing four values. So each Proper Noun gets two tags: `N' for Noun and `geo.' for the type of Proper Noun geographical names, and so on: `N' and `pers.' (names of people), `N' and `merk.' (Company or brand names), `N' and `over.' (other).
| Attribute | Value | Du. example | Du. tag |
| Proper-Noun-Type | geographic | Belfast | N geo. |
| persons | Wilma | N pers. | |
| brand | Droste | N merk. | |
| other | Teleac | N over. | |
The proposed attribute values Noun and Proper Noun are entirely appropriate on the first level for Dutch as well. The Proper Noun subclassification would be introduced as an L2 tag.
