Central Franconian among the Franconian languages.
Luxembourgish is often included within Moselle Franconian, but sometimes regarded as a separate group. The German-speaking Community of Belgium comprises both Ripuarian and Moselle Franconian dialects. The Central Franconian dialects are part of the Rhinelandic continuum stretching from the Low Franconian language area in the northwest to the Rhine Franconian dialects in the southeast. Along with Limburgish, Central Franconian has a simple tone system called pitch accent.
The Central Franconian dialects are of particular interest to linguists because of the tonal distinctions made between different words, for example (Ripuarian) z (tonal accent 1) "sieve" vs. z (tonal accent 2) "she". See Pitch-accent languages#Franconian dialects.
