The voiceless word-final sequences of a fricative and a plosive, in that order, are /-ft/ and /-xt/. Examples of words in which they occur are heft/hɛft/handle, haft, krêft/krɛ:ft/strength, power(s), force, nicht/nɪxt/(female) cousin, and lucht/løxt/air; smell, scent.

The voiced word-final sequences of a fricative and a plosive, in either order, are /-bz/, /-dz/, /-vd/, /-zd/, and /-ɣd/. Some aspects of their distribution are worth mentioning:

• These sequences are mainly restricted to complex (derived) words with a fixed, more or less idiomatic meaning. This does not hold for their voiceless counterparts.
• Most words ending in one of the sequences /-vd/, /-zd/, or /-ɣd/ are loanwords from Dutch. This is not the case with the voiceless counterparts /-ft/, /-st/, and /-xt/.
• The sequences /bz-/, /dz-/, /vd-/, /zd-/, and /ɣd-/ do not occur in word-initial position, nor do their mirror images /zb-/, /zd-/, /dv-/, /dz-/ and /dɣ-/. The voiced fricatives /z/ and /ɣ/ are not allowed word-initially (see the obstruents: the fricatives). In line with the Resolvability Constraint (see onset: sequences of more than two consonants), this also holds of the sequences /bz-/, /dz-/, /zd-/, /ɣd-/, /zb-/, /zd-/, /dz-/, and /dɣ-/. Since /v/ is allowed word-initially (see the obstruents: the fricatives), which also holds of /d-/, both /dv-/ and /vd-/ should be possible word-initial sequences as well, but this is contrary to fact. Their voiceless counterparts, /tf-/ and /ft-/, are not possible word-initial sequences either; this links up with the impossibility of word-initial /dv-/ and /vd-/, which does not count as an independent explanation. On the other hand, the voiceless counterparts of /-bz/, /-dz/, and /-zd/ ‒ viz. /ps-/, /ts-/, and /st-/ ‒ do occur in word-initial position (as complex segments). All in all, voiced obstruent sequences have a far better place in word-final than in word-initial position.

The allowed word-final sequences of voiced obstruents will now be dealt with in turn.

The word foogd is an interference from Dutch; the same holds for the part maagd of the compound drompelmaagd. Most Frisian words with <eu> (/ø:/) are loanwords from Dutch; deugd, jeugd, and freugde, however, have been wholly integrated into the Frisian lexicon. The words ûnbebûgd and ûndoogd are complex (derived) words, as indicated. The sequence /-ɣd/ frequently occurs in the past participle of verbs (of the first weak and strong/irregular class) with a stem ending in /-ɣ/, like (hy hat) liigd/li:ɣ+d/(he has) lied and (it hat hjir) siigd/si:ɣ+d/it has been draughty here (see past participle). In word-final position, /-ɣd/ is realized as [-xt] (see final devoicing: obstruent clusters).

With the exception of seisd, these are all past participles, whether or not preceded by the negative prefix ûn- (/un-/) (see ûn-), derived from a prefixed verb. Some are only formal (pseudo-)participles, since there is no synchronic (complex) verb from which they can be derived (ferweesd, ferbuisd, ferrûsd, ûnbesûsd). The sequence /-zd/ frequently shows up in the past participle of verbs (of the first weak and strong/irregular class) with a stem ending in /-z/, like (hy hat) raasd/ra:z+d/(he has) shouted, yelled and (hy hat) wiisd/vi:z+d/(he has) pointed, shown (see past participle). In word-final position, /-zd/ is realized as [-st] (see final devoicing: obstruent clusters).

Except for hoofd, which is an unmistakable loanword from Dutch, these are also (pseudo-)past participles. The cluster /-vd/ is frequently found in the past participle of verbs (of the first weak and strong/irregular class) with a stem ending in /-v/, like (it hat) kleefd/kle:v+d/(it has) stuck, (it) has been sticky and (hy hat) gnúfd/ɡny:v+d/(he has) leered, peeked; nosed (about) (see past participle). In word-final position, /-vd/ is realized as [-ft] (see final devoicing: obstruent clusters).

Whereas the great majority of the words ending in /-ɣd/, /-zd/, and /-vd/ are loanwords from Dutch, words ending in /-dz/ and /-bz/ are simplex words, which belong to the native part of the lexicon. They will now be treated in turn.

Since all these words end in schwa, /-dz-/ is in intervocalic position, where it is realized as voiced. The word ludze has the variant luts, with word-final voiceless /-ts/ (see final devoicing: obstruent clusters). Also in the diminutive of widze, i.e. widskelittle cradle, /-dz-/ ends up as voiceless: [vɪtskə]; this is the normal pattern for diminutives standing next to nouns with a voiced final obstruent or obstruent sequence (see the phonological domain of final devoicing).

Diachronically, these words have been derived with the suffix -z(e) (/-z(ə)/) from a stem ending in /-{b/d}/. The meaning characteristics they have in common point to a derivation with one and the same suffix. They denote a weak (watery) substance, a (weak) fold of the skin, or a trench (the bottom of which is covered with or consists of sludge).
