Traduko - Portugala-Latina lingvo - Você é o melhor pai do mundo

"Mundi optimus pater es" is a little bit too "uerbum pro uerbo redditum"...

In order to "emphasize" the superlative, here are some 'rationes eloquendi':

1. Unus [omnium] optimus pater es.

2. Vel/longe optimus...

3. Quam optimus...

To my opinion 1 (the stronger) is the better here.

(the strongest) ... is the best

My command of English superlative is very weak as you can see...

Ok chronotribe, don't worry for your english . I will modify my translation .
