蜘蛛（くも、kumo）
- spider

The Japanese word 蜘蛛 (くも, *kumo*) means "spider." It refers to any arachnid belonging to the order Araneae, characterized by having eight legs and the ability to spin silk.

⚫︎あの家には大きな蜘蛛がいます。 Translation: There is a big spider in that house. ⚫︎蜘蛛の巣に虫が引っかかった。 Translation: An insect got caught in the spider's web.

⚫︎蜘蛛 is a common and straightforward word. ⚫︎It's used to describe spiders in various contexts, from casual conversation to scientific discussions. ⚫︎It can be used in both formal and informal settings.

⚫︎The standard way to write 蜘蛛 is with the kanji 蜘蛛 (くも). ⚫︎It can also be written in hiragana as くも. ⚫︎Katakana (クモ) is less common, usually for emphasis or when referring to a specific type. ⚫︎The okurigana (送りがな, the hiragana following the kanji) is usually just the "mo" (も) as in 蜘蛛.

There are no direct synonyms, as 蜘蛛 is the general term for "spider." However, you might use more descriptive phrases: ⚫︎毒蜘蛛(どくぐも, *dokugumo*): "venomous spider" ⚫︎巨大蜘蛛(きょだいぐも, *kyodai gumo*): "giant spider"

There aren't specific antonyms, but you could use words related to insects in general as a contrasting group, or words that express emotions like fear or disgust.

The etymology of 蜘蛛 is not entirely clear. Some theories suggest it may be related to words referring to "weaving" or "thread," likely alluding to the spider's web-spinning ability. Another theory posits that the word's origins stem from the archaic Japanese words meaning "dirt" and "wife".
