Certe ne mi. Mi malamas ilin.
What does this sentence mean?
"Everyone likes competitions" is a better way to say it.
I don't understand why "Ĉiuj" needs the 'j' on the end here.
Me neither. It seems to me that each person likes competitions as an individual; we're not all doing this liking together.
"Everyone likes competitions." is how it would be written.
And when Duo shows me my comment, I see that someone else has already made the same comment.
