What do you know today that you didn't know yesterday?

[Silver]

I still do not know how to trill my R's.

I wonder if it's a necessary part of the language or just an exaggerated accent.

Apparently, it is necessary.

Yes, it does... It is important to be able to correctly pronounce words in any language-- rolling the r's is one of those correct pronunciations.... Sometimes, the rolling of the r's can differentiate words such as:

pero (but) and perro (dog)

buro (chalk) and burro (donkey)

maron (sturgeon[type of fish]) and marrón (brown)

careta (mask) and carreta (cart/wagon)

caro (expensive) and carro (car)

coro (chourus) and corro (ring/circle)

ahora (now) and ahorra [form of verb ahorrar] (she saves)

garo (type of lobster) and garro [form of garrar] (I drag)

bario (barium) and barrio (neighborhood)
