Mr Mandela is often referred to as âKhuluâ, which means great, paramount, grand. The speaker means âGreat Oneâ when referring to Mr Mandela in this way. It is also a shortened form of the isiXhosa word âTat'omkhuluâ for âgrandfatherâ.
I assume 'Pico' is a name. Boku refers to oneself (like 'watashi', 'ore', 'washi', etc.) like 'I' and 'no' indicates possession (for example, 'boku no inu' would be 'my dog' or 'dog of mine' (in reverse order since dog appears at the end in the Japanese sentence) since 'inu' is dog in Japanese).
Today the name Nippon-koku / Nihon-koku (æ¥æ¬å½) is used as a formal modern-day equivalent simply meaning the State of Japan; countries like Japan whose long form does not contain a descriptive designation are generally given a name appended by the character koku (å½), meaning country, nation or state.
