English original

Our Spanish translation

Call me Ishmael. Some years ago—never mind how long precisely—having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world. It is a way I have of driving off the spleen and regulating the circulation.

Llamadme Ismael. Hace algunos años —no importa cuánto exactamente—, teniendo poco o ningún dinero en mi bolsa, y nada en particular que me interesara en tierra, pensé que navegaría un poco y vería la parte acuática del mundo. Es una manera que tengo de ahuyentar el esplín y regular la circulación.

What a faithful Spanish edition must get right

Spanish opens questions and exclamations with ¿ and ¡, and marks dialogue with the raya (—) instead of quotation marks. The punctuation system changes together with the text.

English “you” becomes tú, usted or, in Spain, vosotros. Who speaks formally to whom is decided once for each pair of characters and kept for the whole book.

Latin American or European Spanish is a real choice. It changes pronouns, verb forms and words. You make that choice before translation starts, in the brief you read.

Before translation starts, we build a translator's brief from your whole book: names, terms, tone, typography. You read it and can change it. The brief then guides every chapter. Each passage is read again, independently, against your original, and translated again where that check finds a problem. The finished book gets one whole-book read for continuity. Every change goes into your quality report.

What it costs

A normal 80,000-word novel from English to Spanish costs about $12.99 (Standard) or $24.99 (Premium). Your exact price is counted from your own book — we open it and count every word before quoting — and you see that price, and the free sample, before you pay anything. Prices for other book sizes.

The finished book then gets one whole-book read for continuity. Every change becomes your quality report.
Latin American or European Spanish?Either one. The variant is a line in the translator's brief, which you read and can change before translation starts.
