The majority of these are anglicised from Arabic, Chinese, Hebrew, Inuktitut, or other languages which do not use the English alphabet, with Q representing a sound not found in English. For example, in the Chinese pinyin alphabet, qi is pronounced /tʃi/ by an English speaker, as pinyin uses ``q'' to represent the sound (tɕh), which is approximated as (tʃ) in English. In other examples, Q represents (q) in standard Arabic, such as in qat, faqir and Qur'ān. In Arabic, the letter ق, traditionally romanised as Q, is quite distinct from ك, traditionally romanised as K; for example, قلب /qalb/ means ``heart'' but كلب /kalb/ means ``dog''. However, alternative spellings are sometimes accepted which use K (or sometimes C) in place of Q; for example, Koran (Qur'ān) and Cairo (al-Qāhira).
