slang for 'modern'

[Itasan]

NAUI
Borrowing the English word 'now' and putting
the Japanese adjectival suffix 'i', a new
slang word is heard 'now-i' ('naui' in Japanese
spelling). I think it can be called a slang word
for 'modern'. 'naui fashion', 'naui way of speech', etc.
Is there any such slang word in English? 'nowbie'? No.
Thank you.

Additionally, "in"; e.g., It's in. Cf. It's out. Japanese, out-i (?)

Itasan, would that suffix be related to long "ii", meaning good?

Thank you very much, everybody.

'Out-i' - very interesting, but it's impossible, IMHO. LOL
>>Itasan, would that suffix be related to long "ii", meaning good?<<
Oh, you know it very well. ii = good. It seems it doesn't apply in this case. Or maybe it does. Sorry it's difficult.
Adjectives ending in 'i': oishii, mazui, subarashii, so 'ii' might be one of them. Sorry I'm not a good Japanese teacher.

BTW, "Your hat's in today." "His glasses are out."
Do they work, meaning 'fashionable' and 'unfashionable'?

Yes. "That hat's in (style) and that hat's [i]out[/u] (of style)". The heading "In & Out" is fairly popular in fashion magazines. It heads articles that describe what's in (fashion) and what's out (of fashion).

A note on Japanese adjectival -i.
I get it, Itasan. Even adjectives that take the non-Japanese adjectival particle, > Chinese na; i.e., kirei na, okii na, also end in -i. The new word "nau-i" is an analogical development. That is, add -i to make a word an adjectives, even add it to foreign words; i.e., "now" (adverb) => "now-i" ~ "nau-i" (adjective), meaning it's in (fashion) right now.
