That’s right. KAIKKIALLA is a linguistic HAASTE for the vast majority of people.
Just like: Ahmas, Kivisuo, Valkama, Ranua or Lentiira.
HAASTE [ˈhɑ̝ːs̠te̞(ʔ)] is a challenge, namely KAIKKIALLA [ˈkɑ̝i̯kːiˌɑ̝lːɑ̝].
Between Lappalanjärvi and Rapojärvi - that's Valkeala. Not easy! If you want to be able to do something, you have to do it. Do it again and again. Often hard work, but then ... marvellous!
SIPOO [ˈsipɔː] is easy, isn't it? Because not everything is difficult. Nevertheless, hard-won achievements are remembered.
