For A While
For Some Time
adverb, の adjective
When you do something temporarily, you're only doing it for a while. It's not permanent — however long it lasts, it's just for some time.
暫く refers to a stretch of time that's not too long, but not super short either — just somewhere in between. How long, exactly? It kinda depends on the speaker. If it feels like a while to you, then hey, it's a while!
Keep in mind that the kanji form is quite formal, so it's more commonly written in kana, like しばらく.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
You've been waiting for a while and nothing has happened yet, so you start singing a sheep ballad (しばら). This ballad helps you sleep by counting sheep. If you manage to doze off for some time, time will surely pass faster, and then something might happen!
暫くお待ち下さい。
Please wait for a moment.
暫くの間、旅に出ます。
I'll be traveling for a little while.
暫く会ってないし、今度お茶でもしない？
It's been a while since we last met. How about grabbing tea sometime?
悪阻がひどくて、暫く全然家事ができてないんですよね。
I haven't done any housework in a while because I have terrible morning sickness.
