Ninja
That "image" to the left, which is really just a picture of text, is something I've been seeing on Facebook lately. It's kind of funny, but it also makes perfect sense, logically.
Because Ninja, like Katana, is originally a Japanese word that has only been adopted into English because it has been used so often. Probably because of TMNT. The point here, though, is that Ninja, like all Japanese words, does not add an "S" to the end to become plural. Many Ninja are spelled the same as one Ninja. So that's probably how the Ninja were hiding from the thesaurus so well. LOL.
nin·ja [nin-jə] n. pl. a member of a class of 14th-century Japanese mercenary agents who were trained in the martial arts and hired for covert operations such as assassination and sabotage
Synonyms: there are no direct synonyms for this word, but some related words are: ninpo, ninjitsu, Kunoichi, Shinobi, monomi
Etymology: Ninja is an on'yomi (Early Middle Chinese-influenced) reading of the two kanji "忍者". In the native kun'yomi kanji reading, it is pronounced shinobi, a shortened form of the transcription shinobi-no-mono (忍の者). These two systems of pronouncing kanji create words (ninja/ninsha or shinobi-no-mono) with similar meanings.
