What to know when interpreting Spanish
Every language has grammar that an interpreter must handle correctly. These are the Spanish features that the fewest other languages in the world share, according to the World Atlas of Language Structures (WALS).

1.4%
of the world’s languages share this trait
Spanish turns a statement into a yes-or-no question by reordering the words or raising the voice alone, so an interpreter who misses the tone misses the question.
3.2%
of the world’s languages share this trait
Spanish builds its perfect tense from the verb for having, and that form tells an interpreter whether a symptom is finished or still going on.
4.8%
of the world’s languages share this trait
Spanish marks gender in “we” and “you” as well as “he” and “she”, a detail English drops that an interpreter must carry to keep clear who a patient is talking about.
