Everything that happens in the world can happen or be done in many ways. It is therefore not surprising that one finds a multitude of adverbs used to express all of this. The list below is anything but complete. Some adverbs have pronominal properties, e.g. so ‘so, in this way’. However, the vast majority have a more specific meaning (e.g. stapfouts ‘walking pace’). Many such specific adverbs are adverbially used adjectives (such as fluch ‘beautiful’). Adverbially used adjectives can also be comparative or superlative, as in the examples below:

Note that the adverbial superlative may be expressed as a PP consisting of the preposition ap ‘on’, the definite neuter article and the superlative of an adjective. PP superlatives are also found in West Frisian. The word ieuwen ‘in short’ may function in certain contexts as an existential quantifier of manner:

Below some adverbs of manner are given:

An interesting manner adverb is stilkens ‘silently’, as it has the form of the plural diminutive of the adjective stil ‘quiet’. This phenomenon is also found in Dutch and West Frisian. Another interesting case is fräiwäch ‘bluntly’, which consists of the adjective fräi ‘free’ followed by the adposition wäg ‘away’. The latter is an old loan from Low German, but this type of compound also exists in West Frisian. Note that stilken ‘silent’ is an adjective in present-day Saterland Frisian, and it may exhibit agreement. Perhaps it is a back formation from the adverbial stilkens, in which the adverbial burden shifted from the plural diminutive to the plural, so that the diminutive was reanalysed as apart of the adjectival stem.

Temporal adverbs refer to time, chronology, duration, or frequency. There are some temporal adverbs with pronominal or quantificational properties, see 8.1: these clause adverbials can also be used to modify VPs. The difference is subtle between a reading in which a clause is modified and the reading in which a VP is modified. Other temporal adverbs include:

It can be noted that jäärsen occur without a schwa when used attributively, whereas it is marked with a schwa in case it occurs on its own.

See also 8.1. Some examples of frequency adverbs include:

These frequency adverbs are all marked with –s, which historically derives from a genitive plural. It is unclear whether the determiner fuul ‘much, many’ can also be used as a frequency adverb. The following example shows that adverbs of time precede adverbs of frequency:

All adverbs of place are similar in meaning: they refer to places. Adverbs of place appear in different categories and forms. Some can be used deictically, interrogatively, negatively, and indefinitely, just like pronouns.

Wier ‘where’ is used as the adverbial interrogative of place. In addition, it is also used as the adverbial relative of place, instead of deer ‘there’, which has become antiquated. To illustrate, consider the following:

The deictic prefix ke- in kedeer ‘there’ and similar cases is derived from kiek ‘look’. Note that adverbials of place are not derived from APs.

Degree adverbs provide information about the degree of the situation or event described by the Verb Phrase (VP). Adverbs of degree are words like the first element of the following phrases: aiske groot ‘very big’ or 'n bitjen leet ‘a bit late’. Expressions such as hoast dood ‘almost dead’ are also included in this overview. High degree adverbs are very numerous. The reinforcing element jo ‘absolutely’ is a particle that shades off in being a very frequent filler without much meaning. See also AP, chapter 3.
