'tr' confusion

Good day, everyone!
Could anybody explain me the following situation.
If I'm running similar script:
Var2="Anna Kurn"
echo $Var | tr -t  "$Var" "$Var2"

Why the output is :
anna KurniKova

instead of Anna Kurnikova?
Thank you in advance for any explanations

Why are you telling it to truncate the first var? I'd suggest just running tr as normal without the truncate commandline option - should do what you want.

Edit: It's also not a supported flag on many implentations of tr so isn't very portable

What i'm trying to achieve is to combine those two variables so the output would look like a proper name. If i'm running 'tr' on it's own the result is really messy, looks like a single letter substituion:
 nnnn nurnnnnnn

And the reason for truncating, is to bring both Var's to equal lenght.
