Strong enough

Question

I was watching a show in which they used "tan fuertes" to mean strong enough.

"Los dientes de Thompson - Los únicos dientes tan fuertes como para comer otro dientes"

Thompson's Teeth - The only teeth strong enough to eat other teeth.

Is that the best way to say strong enough? Why is that "como" in there after fuertes? Shouldn't it be - "Los únicos dientes tan fuertes para comer otro dientes"

Answer 1

tan...como is the Spanish way to say as...as.

Tan rojo como un jitomate. Tan chistoso como un payaso.

Answer 2

I'd say the como is there because it's not a direct translation of 'strong enough' but instead it's more like 'so strong as to be able to'.
