Luxembourgish phonology

[1] Morpheme-final /n/ undergoes both internal and external sandhi: it is deleted unless followed by a vowel, a homorganic (i.e. apical) noncontinuant, i.e. [n t d ts dz tʃ dʒ], or [h].

Furthermore, some unusual consonant clusters may arise post-lexically after cliticisation of the definite article d' (for feminine, neuter and plural forms), e.g. d'Land [dlɑnt] ('the country') or d'Kräiz [tkʀæːɪts] ('the cross').

For instance, sech eens (phonemically /zeχ ˈeːns/) is pronounced [zəˈʑeːns],[6] although this article transcribes it [zəʑ ˈeːns] so that it corresponds more closely to the spelling.

It is also sporadically retained in the environments where it is vocalized after other long vowels, which is why the merger with the monophthong [aː] is assumed to be phonetic, rather than phonemic.

The fricativization and devoicing to [χ] also occurs whenever the non-prevocalic /r/ is retained between /aː/ and a fortis consonant, as in schwaarz [ˈʃwaːχts] 'black', alternatively pronounced [ˈʃwaːts].
