Chinese characters
When learning how to write hanja, students are taught to memorize the native Korean pronunciation for the hanja's meaning and the Sino-Korean pronunciations (the pronunciation based on the Chinese pronunciation of the characters) for each hanja respectively so that students know what the syllable and meaning is for a particular hanja. For example, the name for the hanja Shui  is mul su (mul-su) in which mul (mul) is the native Korean pronunciation for "water", while su (su) is the Sino-Korean pronunciation of the character. The naming of hanja is similar to if "water" were named "water-aqua", "horse-equus", or "gold-aurum" based on a hybridization of both the English and the Latin names. Other examples include saram in (saram-in) for Ren  "person/people", keun dae (keun-dae) for Da  "big/large//great", jageul so (jakeul-so) for Xiao  "small/little", arae ha (arae-ha) for Xia  "underneath/below/low", abi bu (abi-bu) for Fu  "father", and naraireum han (naraimreum-han) for Han  "Han/Korea".
