Please note that terms  used in the martial arts often are specialized terms and may be used differently in conversation. Japanese who are not martial artists are often not familiar with these expressions. For example, the term "nukiuchi" means "suprise attack" in martial arts but in schools it means "pop quiz".

Pronunciation: i always sounds as ee, as in skeet; u always sounds as oo, as in tool; o always sounds long o, as in pole; a always sounds as ah, as in father; e sounds eh, as in bet.  Often the last vowel of a word is not fully pronounced, especially if is a u, or an i   " r" in Japanese has a "d" sound, so that geh-ri (kick) is pronounced more like geh-di.  Japanese words that begin with "K" often change the k sound to g when the word follows others in a compound, i.e. " kumite", but " kihon gumite".
