行ってらっしゃい I know that 行ってらっしゃい is a formal response to 行って来ます and English translations could be "Have a good day". But what does 行ってらっしゃい actually mean? It has 行 in it, and maybe 行って is the て form of 行. But where does らしゃい come from? I'm sorry if this is a stupid question.

Is there a Japanese word that uses the kanji 二 with the on-yomi ジ ? I am learning the on-yomi of the kanji and it is helpful to learn words that use each sound.

hiragana or kanji? I'm a beginner at the Japanese language. I'm starting to learn kanji. I don't use Japanese for work. I've been told that sometimes it is better to write with hiragana only, without kanji, to express less formality. In particular, for「きれい」、instead of 奇麗 or 綺麗. Is that true for all words, or just some words? Is anything on the internet formal enough for kanji? I'm not sure when I should be using kanji. Thanks!

tangorin.com syntax Hi. I like to use tangorin.com to look up Japanese words. (If this link doesn't work, this is just a search for きれい on tangorin.com .) Example: https://tangorin.com/kanji?search=%E3%81%8D%E3%82%8C%E3%81%84 きれい☆《奇麗・綺麗・暉麗old》キレイKIREI☆ My question is, does the information inside the 《 》marks mean that those kanji can be used to spell きれい ? So, does 奇麗 mean きれい ? Does 綺麗 mean きれい? Does 奇麗 mean the same as 綺麗 ? Thank you!

すみません: 済? 住? Is すみません (excuse me, pardon me, thank you) related to 住みません (to not live, polite)? I see that すみません is spelled 済みません but I don't see how 済 (すます) becomes 済みません.

dumb question: particles and janai わたしは　おちゃが　すき　じゃない Is ga correct here, or should it be wo? やまださんはがくせえじゃないです Does gakusee need a particle? Is it optional? Do nouns always need particles? One of the above sentences ended in janai desu, and one ended in janai. Is it more correct to add desu? Is it informal to leave desu off?
