How to Sound Profound in Japanese
While knowing only three words.

Zero fluency required; let these three little words do all of the heavy-lifting.
Saa (さあ)
It sounds exactly like a sigh. Use it to mean ‘it is ineffable’ or ‘this will indeed puzzle philosophers for the centuries to come’.
Naruhodo (なるほど)
‘You have made a very eloquent point. The scales have fallen from my eyes. Now I understand.’
Soudesuka? (そうですか?)
‘Is that so?’
But what’s this, you want to know, will this really fool people into thinking you’re not only fluent in Japanese but also incredibly profound?
…Saa.
