The Eurotra dictionaries have the attribute whmor, with the three possible values int, rel and none, which serve to distinguish between interrogative, relative and other adverbs:
| Attribute | Value | Sp. example | Sp. tag |
| Polarity | muy | ||
| Wh-Type | int | dónde, cuándo, cómo | whmore=int |
| rel | donde, cuando, | whmore=rel | |
| non-Wh | aquí, ahora, así | whmore=none | |
