Title:
Chinese_characters

Context:
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 水 is 물 수 (mul-su) in which 물 (mul) is the native Korean pronunciation for "water", while 수 (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 사람 인 (saram-in) for 人 "person/people", 큰 대 (keun-dae) for 大 "big/large//great", 작을 소 (jakeul-so) for 小 "small/little", 아래 하 (arae-ha) for 下 "underneath/below/low", 아비 부 (abi-bu) for 父 "father", and 나라이름 한 (naraimreum-han) for 韓 "Han/Korea".
