Why do you say le doy el libro a Juan — doubling the indirect object?
The answer isn’t the translation — it’s the middle layer, where English word order is rearranged into Spanish logic before a single word is swapped.
The thought · English
I give the book to Juan.
The structure · English in Spanish logic
To-him I-give the book to Juan.
The Spanish
Le doy el libro a Juan.
The rule
Spanish often doubles the indirect object: the pronoun “le” (to him) appears even though “a Juan” already names who. It is not redundant — it is the normal, idiomatic pattern, almost obligatory when the recipient is a specific person. “Le” previews who receives, then “a Juan” specifies. Dropping “le” sounds stilted to native ears.
Reading the structure is step one. Feeling it is the moat — watch the words physically rearrange, then say your own sentence and the bartender answers.
