"Son sustancias muy fuertes."

Translation: They are very strong substances.

[AnCatDubh]

Strong substances as in diamonds or heroin?

[ph516503]

I would guess more like heroin. Strong in the sense of "hard" like a diamond would probably be "dura"... but like English, I'm guessing both could be correct, depending on context.

Also did not accept: The substances are very strong.

[Christophe2068]

That would have been, "Las substancias son muy fuerte."

When "son" is at the beginning of a sentence it translates to "They are."

[Talca]

Yeah, I realized that after I thought about it. Thanks for comment. Gracias.

[andygravity]

Thanks for the explanation.

[HarpoChico]

In new-speak 'substances' tend to mean drugs...

Double-plus ungood.

Oh how the español word order can trick my anglophonic brain at times.....

[DABurnside]

"They are very powerful substances" was not accepted.

[MarinaKots2]

I still can't understand in which cases the adjective goes before the noun and when it goes after the noun

[Exordium]

Are "sustancias" and "substancias" correct?

[Ashley394144]

Could you say, "son muy fuertes sustancias"?
