It is pronounced Ninja-GO isn't it? Not NinJAHgo?

Lego fans will know what I'm talking about.

Why would you say NinJAHgo?

I am not prepared to hear IABU btw

patronised me beautifully

That sounds so nice!

I want to be patronised beautifully!

Depends whether you want to use the pronunciation of the words's country of origin or the uk adapted version. As someone pointed out, Japanese has equal emphasis on syllables, so nin-ja-go, all equal stress. Same as ka-ra-te, but of course UK pronunciation would be ka-rat-tee, with a higher emphasis on RA. Talk to a Swede and they will tell you its I-kay-ya, not eye-key-er as British people would say.

It come down to this, tell your DS to say it the same way his friends do and say it in your own head the way you want to!

Nin-jay-go. No idea why. It just is!

YAB v v v v v v v U!

Good thinking bogeyface. I don't want DS shunned :o
