The paradigm of interrogative pronouns is sensitive to the feature <person>. Subjects and objects to V which are presupposed to be persons are questioned with the word wäl ‘who’. Subjects and objects which are presupposed to be [<-person>] are questioned with the question word wät ‘what’. There is no case or gender difference between the subject and object interrogative pronouns. Note that the situation is different and complicated for adpositional objects. On these, see: R-pronouns (9). Some examples of subject questions are given below:

Subject questions with the personal interrogative are far more numerous than object questions with the personal interrogative. Object questions tend to feature the impersonal interrogative. Some examples of object questions are given below:

Predicate nominals can also be questioned. Furthermore, it is possible to postmodify a question word with a possessive PP which restricts the scope of the interrogative phrase. An example is given below:

The topical or minimal answers to Wäl? ‘who’ would be: Die! ‘He!’ Or: Hie! ‘He!’ Or: Ju! ‘She!’. Or: Do! ‘They!’. The topical answer to ‘Wät? ‘What?’ would be: Dät! ‘That!’

Questions targeting the object of an adposition can be made in two ways. The R-pronoun wier ‘where / what’ can be used.

The R-pronoun can be found by itself at the beginning of the clause, as in West Frisian, or it can take the adposition along, as in German. The R interrogative tends to be reserved for non-persons. But when it functions as a relative, it can take a human antecedent. It is nowadays often found with prepositional complements which are locations, but not necessarily:

The more common way of targeting an adpositional complement, at least nowadays, is by having the preposition and the question word at the beginning of the clause (mäd wäl instead of wier ... mäd):

It is unclear whether the impersonal interrogative is also used in this way (mäd wät instead of wier ... mäd).

Possessors can be questioned by means of the genitival form of the interrogative for persons or the doubling construction can be used:

The genitival form is somewhat bookish, or it sounds a bit like a German interference. The doubling construction is characteristic of the spoken language in Dutch, Low German and in the Frisian languages.

According to Fort (2015), the interrogative article word wäkker ‘which’ has the following forms, but they seem to have been regularised recently, as indicated in the last row:

	MSC SG	FEM SG	NTR SG	PL
Fort (1985)	wäkker	wäkke	wäkker	wäkke
regularised	wäkker (wäkken)	wäkke	wäk	wäkke

So there is variation. In the source texts, wäkker ‘which’ is sometimes inflected for the non-nominative, as in the following example:

Some sources in the Kramer archive use an unbent form wakker for all genders in the singular and plural:

The interrogative pronoun wät ‘what’ can be used adjectively, though this is old-fasioned, giving it almost the same meaning as wäkker. An example is given below:

The question word wät ‘what’ implies that there is a free choice. The word wäkke ‘which’ is also used as an indefinite pronoun meaning ‘some’, see: Existential quantification (7.2).

An attributive question can be formed with the special construction used for kinds, by means of the question word wät ‘what’ followed by the adposition foar ‘for’ followed by a noun. The question word can either be adjacent to the PP restricting its scope or it can be separate from it. Some examples are given below in which the question word and the restricting PP are put in bold:

The last example is especially interesting. The NP targeted by the attributive interrogative is the question word wäkke ‘which’, here used as an indefinite quantifier.

The degree of an Adverbial (AP) can be be questioned with the question word wo ‘how’, as in wo leet ‘how late’, wo jädden ‘how willing’, and so on.

Adverbials of time and frequency

The interrogative of time is wanner ‘when’. An example is given below:

The interrogative of frequency is the phrase wo oafte ‘how often, how many times’. The topical or minimal answer to Wanner? ‘When?’ would be Dan! ‘Then!’.

Adverbial of manner

The adverbial of manner is: wo ‘how’. Some examples are given below:

The answer to such a question can be a PP or a discourse of several sentences explaining how something is done. The topical answer to Wo? ‘How’ would be: So! ‘So!’.

Adverbial of reason

The question word foar an adverbial of reason is: wieruum ‘why’. Some examples are given below:

The topical pronominal answer would be deeruum ‘that’s why’, as in the following sentence:

English doesn’t have a topic equivalent to the interrogative of reason so it has to make do with the unmarked demonstrative and a copula and the interrogative of reason: that’s why.

Adverbial of place

The adverbial of place is wier ‘where’. Some examples are given below:

The adverbial of place can also be used to question adpositional objects. The topical pronominal answer to Wier? ‘Where?’ is Deer! ‘There!’.
