Questions & Answers about Saltó sin paracaídas; fue muy arriesgado.
Why does paracaídas end in an -s if the English translation is singular ("a parachute")?
Why does this sentence use fue instead of era for "it was"? Aren't we describing a situation?
Would arriesgado change to arriesgada if we knew a woman was the one who jumped?
No. The adjective arriesgado is not describing the person who jumped; it is describing the action of jumping itself. When an adjective describes an action, an abstract idea, or a neutral "it" (like the event of the jump), it always defaults to the masculine singular form.
Since this lesson is about intensity relative clauses, how could I rewrite "it was very risky" to mean "you don't know how risky it was"?
