“Tico” is a colloquial term for a native of which Central American country?

In Italian we have the suffixes 'ino' and 'one' for little and big. For example it's quite usual to sign a message to friends with either baccino - a little kiss or baccione - a big kiss.

SilentElephant82086, tico is not Spanish for uncle. Tío is Spanish for uncle.

definitely appreciate reference of beer & joint in Dutch ;)

Colombians don't call themselves ticos but they too use the tico suffix to form a a diminutive word

bflowers84, Take a look at a map, Costa Rica is just northwest of Panama.

in swiss german they add "li" to the end to diminuate, bear becomes bearli

for diminutive words we use jamo in our Visayan dialect

Lived in CR 20 years ago and never heard them use "ico" or "Ica". Been living in Nicaragua for the last 20 and here the people use "ito" and "ita" prolifically. "Aguita" for example, when asking for a little water!

Another guess
