This word has been borrowed into the Swahili language, where it is used also as a title of respect for revered members of a community, religious or secular, roughly equivalent to the English "Sir". In the mostly Muslim region of West Africa, the root has been proposed as a source for the words Mallam (Hausa language) and Maame (Wolof language), which are used to denote Islamic scholars, or in areas practising folk Islam or folk magic, a local shaman. Among the Hausas the word Mallam is additionally used as equivalent of English Mr. A more likely explanation for this word (and for the Swahili mwalimu) is the Arabic word mu'allim (), which in Moroccan Arabic is pronounced "m'allam" and means 'teacher' or 'master' in a Qur'anic school. Difference in titles Mullah and Maulvi among Muslims in South Asia 
In the Central Asian and South Asian / Indian subcontinent context, where "Mullah" does not carry a formal sense, Maulana is often the word of choice for addressing or referring to Muslim religious scholars that are respected, while Mullah is used often derogatorily for people the speaker considers to be more rabble-rousers than scholars. Although the words Maulvi and Maulana are interchanged in the Indian Subcontinent as a title of respect, Maulana is more often associated with formal qualification following study at a madrassa or darul uloom and Maulvi is usually more a general title for religious figures. In Bangladesh, in the government Aliyah madrassa system, Maulvi is also associated with formal degrees for those who have passed the course of Maulvi (basic), Maulvi Alim (intermediate) or Maulvi Fazil (advanced).
