Like other Eastern Catalan dialects, unstressed /a/ and /e/ are realized as schwa [ə], and [u] substitutes unstressed /o/. It is has only five stressed vowel, the smallest number of any Catalan dialect: /i e a o u/.
There are some instances of historic stressed /o/ that has changed to /u/: canigó > canigú.
As in Balearic dialect, final a is not pronounced in words ending with ia if the stress is before the penultimate syllable.
Northern Catalan has a large body of words imported from French and Occitan. It also features some grammatical forms and structures that are typical of Occitan, such as the use of a lone post-verbal pas, rather than a lone preverbal no to express basic negation (Northern Catalan canti pas vs. Central Catalanno canto, 'I don't sing' or 'I'm not singing'); pas is also used in some other Catalan dialects for emphasis but always with no before the verb (Central Catalan no canto pas, 'I do not sing' or 'I am not singing').
