Precision: the mistakes even natives make

Dequeísmo, queísmo, “hubieron”, “detrás mío”, sino / si no, porque / por qué… Write Spanish that a strict editor would sign off.

At C2, the goal is precision. These are the points where even educated native speakers slip, and where the RAE norm is clear. Each sentence has exactly one problem: find it and correct it.
