Hollman is a surname of Germanic origin, which is phonetically pronounced as /ˈhɒlmən/. The first syllable 'hol' is pronounced with an open o sound /ɒ/ and the second syllable 'man' is pronounced with a short a sound /æ/. The double 'l' in the spelling represents a consonant sound that is pronounced as a prolongation of the l sound /l/ in English. Thus, the spelling of 'Hollman' follows the English convention of using double 'l' to represent the prolongation of the l sound.
