Utilizamos “so” (tan, así, entonces) y “such” (semejante, tal, tan, tanto) para añadir énfasis, mostrar sentimientos extremos o para dar la opinión sobre algo. La diferencia entre los dos está en cómo los utilizamos en la formación de las frases y en el tipo de palabra al que acompañan.
SO
So puede acompañar a un adjetivo, adverbio o a un nombre contable o incontable. Pero nótense la diferencia de cuando acompaña a unos o a otros:
- So + adjective/adverb
The day is so cold that we can’t go skating.
You are driving so quickly.
- So + much/little + uncountable noun
There is so much furniture in the living room.
- So + many/few + plural contable noun
There are so many plants in the garden.
There were so few people that the place seemed almost empty.
SUCH (A)
Such puede acompañar a sustantivos contables o incontables, sin distinción. Esa sería la estructura:
- Such + (a/an) + (adjective/adverb) + NOUN
My son became such a man.
I don’r want to drink such water
It was such a good movie that I saw it twice.
My teacher gave such an interesting speech
Here are such bad politicians in Spain that the country is now facing a deep crisis.
