There is considerable evidence for the presuppositional nature of the order in which the adverb precedes clause negation. Examples of this order can be found on the internet and in the Frisian Language Corpus. They are all strongly presuppositional, as is illustrated by two of these examples, which are given below:

The marked order turns out to be specifically correlated with correcting the set of assumptions of the addressee that is part of the presuppositional context of the speaker. The adverb of manner of degree refers as a pronoun to an assertion or opinion. This order may also show up in tag questions. So either order can be found:

The tag question is neutral in (4a). The tag question in (4b) strongly presupposes that the previous assertion is true, and so it is more emphatic.

The pronominal adverb and negation can also be used on their own as a presuppositional negator. The combination of the two items forms a proposition all by itself. They negate a presupposition that is loosely associated to the previous context, and made explicit and negated in the clause following the presuppositional negator. An example is given below:

Here the first clause may give rise to a presupposition that they do not work hard. This presupposition is both made explicit and cancelled by sa net so not > do not think, but the exact nature of the presupposition only becomes clear when the following clause has been uttered. This clause allows the hearer to reconstruct the exact presupposition that is cancelled by the combination of the pronominal adverb and negation. Note how Frisian and English arrive at the intended interpretation. The English translation uses double negation and explicitly invokes what the addressee might think according to the speaker. The Frisian sentence cancels a presupposition ascribed to the addressee, a presupposition which must be reconstructed from the relevant sequence of utterances. Anyhow, this use of sa net so not > do not think refers both backward and forward in a sense. The pair of items must be followed by a clause that explains the use of these two items.

The pronominal adverb refers to an assertion or opinion, that is, to a proposition. However, it may also refer to a proposition denoting the negation of a property, as in the following example:

In the examples above, the pronominal adverb referred to a proposition.

The pronominal adverb may also refer to a high degree. If this degree involves a property, then it usually involves an ethical degree. The pronominal adverb may be said to refer to the high degree of an ethical predicate in the examples below. This predicate may be paraphrased as either 'good' or 'bad'. The example in (7a) involves the denial of a high degree of badness, whereas the example in (7b) involves the denial of a high degree of goodness:

The example in (7b) involves a so-called balance construction, which is found in both Frisian and Dutch. It involves a disjunction of which the second disjunct is in the scope of the first in some sense.

Furthermore, the pronominal adverb can also refer to the presupposed degree of whatever is denoted by a verb, as in the following examples:

These examples all involve the negation of an equative degree, although there is no overt adjective. The equative degree is signalled by the phrase introduced by as as, which provides the standard of comparison. The examples all specify the denial of a high degree of intensity.
