Danish has a very large vowel inventory consisting of 27 phonemically distinctive vowels, and its prosody is characterized by the distinctive phenomenon "stød", a kind of laryngeal phonation type. Due to the many pronunciation differences that set apart Danish from its neighboring languages, particularly the vowels, difficult prosody and "weakly" pronounced consonants, it is sometimes considered to be a "difficult language to learn, acquire and understand", and some evidence shows that children are slower to acquire the phonological distinctions of Danish compared to other languages. The grammar is moderately inflective with strong (irregular) and weak (regular) conjugations and inflections. Nouns and demonstrative pronouns distinguish common and neutral gender. Like English, Danish only has remnants of a former case system, particularly in the pronouns. Unlike English, it has lost all person marking on verbs. Its syntax is V2 word order, with the finite verb always occupying the second slot in the sentence.
