"Ellos tienen buenos principios."
Translation:They have good principles.
I kind of want them to accept "principals" as a spelling error...this has been a major spelling problem of my life. I remember once a 6th grade teacher saying "remember the person is princi-pal, cause they are your pal!" Maybe that mental trick will help somebody else who keeps missing this one, it certainly hasn't cured me of this spelling mistake >.<
