Oh hi! Thanks for the ask!
Hm... I have quite a lot of words i like actually, it's kinda difficult to pick just one
In English i really love the wordr "actually", "apparently" and "specifically" - I even keep using them outside of english 🤭. I also really love the word "silly". Some of the other words i like include but are not limited to: aargh, augh, alas, bah, beans, blegh, bouquet, bewildered, delightful, dove, ethereal, gah, grrah, grasp, hmph, hollow, jade, loo, meh, mlem, muffler, objective, obscene, perplexed, peas, petrol, pleh, skedaddle, syrup, telly, thou, thee, unnecessarily, woh, woah, yikes, and most of medical terms for some reason.
When it comes to ukrainian i honestly love the entire dictionary... There are still so many words i don't know too. But my most favorite include: філіжанка ([filizhanka], cup), горнятко ([hornyatko], cup), бульбашка ([bul'bashka], bubble), пекло ([peklo], hell), чудернацький ([chudernac'kyi], weird), блискавиця ([blyskavycia], lightning), конче ([konche], when you really need something), тямити ([tyamyty], understand a lot about something), квапитися ([kvapytysia], to be in a rush), отакої ([otakoi], "oh wow", "what do you know", "oh my"), затишок ([zatyshok], cozyness/comfort), опалення ([opalennia], heating in the house), жарт ([zhart], joke), гармидер ([garmyder], commotion, chaos, fuss), мармиза ([marmyza], slightly vulgar term for face), сірники ([sirnyky], matches), сірка ([sirka], sulfur), стеля ([stelia], ceiling), and most of chemical terms specifically. There is one chemical compound that is considered one of the longest words in ukrainian language that i memorised in highschool: Дихлордифенілтрихлорметилметан, which translates to Dichlorodiphenyltrichloroethane (or simply DDT)
In russian language i mostly like the old words that are rarely used nowadays. Some examples include: авось ([avos'], perhaps), брань ([bran'], swearing or war), булатный ([bulatny], made out of damascus steel), всучить ([vsuchit'], to foist onto), длань ([dlan'], palm), ежели ([ezheli], if), затрапезный ([zatrapezny], shabby), зеница ([zenitsa], eye pupil), канделябр ([kandeliabr], candelabra), колымага ([kolymaga], a carriage basically, but now it's used as an ironic name for an old car that is falling apart), латы ([laty], plate armour), лик ([lik], face), лягать ([liagat'], kick someone with hind feet), огниво ([ognivo], tinderbox apparently), перст ([perst], finger), подол ([podol], hemline), пола ([pola], hemline too), реверанс ([reverans], curtsy), сусек ([susek], this thing... corn bin, but small and built into a grain house), уста ([usta], mouth), чело ([chelo], forehead), челядь ([chel'ad'], underlings or servants), шибко ([shibko], when you really need something). One other word i recently memorized is "квазиантихороводоведофилофобофаги" and i will not explain it to you because i'm way too lazy 🥲. All i can say is it's a made up tongue twister word
In Japanese it's キラキラ (kirakira), which is an onomatopoeia for sparkling ✨:). I like japanese language as a whole honestly, so the situation here is a little similar to ukrainian, except i don't really know a lor of words in japanese... ߹𖥦߹. Some other words i really like in japanese are 絶望 (zetsubou), which means despair 翼 (tsubasa) meaning wings, 筋 (suji) which can mean a surprising lot of things... including muscles, which i thought was the only transtation lol, 死神 (shinigami) which means god of death, 死 (shi) meaning death, わんちゃん (wan-chan) which is an affectionate term for dog, にゃんちゃん (nyan-chan) afaik an affectionate term for cats, but i might be wrong... 心臓 (shinzou) for heart, 罰点 (batten) for a X mark, ぐるぐる (guru guru) - an onomatopoeia for spinning in circles, 転生 (tensei) for reincarnation, どこ (doko) fpr where, 寒い (samui) for cold, キモい (kimoi) for gross, 口寂しい (kuchisabishii) for a feeling of wanting to eat something when you're not hungry, 孤独 (kodoku) for isolation, 熱い (atsui) for when an object is hot to touch, 痛い (itai) for painful, 魔法 (mahou) for magic and umai for tasty but i couldn't find how it's written in japanese...
