Aseri: Sweaty anxiety
Today's word is 焦り あせり aseri - anxiety.
The verb form (to be anxious, nervous, to mildly panic) is 焦る あせる aseru.
You might also use it with 感じる かんじる kanjiru - to feel (verb) - 焦りを感じる あせり を かんじる aseri o kanjiru to mean 'to feel anxiety'.
The ase part of 焦り or 焦る sounds the same as 汗 あせ , which means sweat. In Japanese, words with different kanji and meanings that sound the same are often connected (which is why the number 4 (四), which can be read shi, the same as 死 - death, is considered unlucky). So I don't think it's a coincidence that anxiety, which can make you sweat, sounds the same as the word for sweat.
If you know someone with a tendency to be anxious and worry, you could give them a T-shirt printed with:
焦らないでマイペースでいこう! あせらないでまいぺーすでいこう! aseranaide maipe-su de ikou!
(Don't be anxious (don't sweat), go at your own pace! (マイペース maipe-su is 'my pace' meaning 'your own pace').
(Incidentally, the word for a big, all-out panic is パニック panikku - yep, another imported word.)
