Spot the double reading, repair it on the spot, and be understood the first time — out loud.
Most Spanish ambiguity comes from three places, and each has a standard repair. Modifier attachment: vi al hombre con el telescopio — who has the telescope? Move the modifier (con el telescopio, vi al hombre) or add a clarifying clause. Negation scope: no vio a todos can mean 'didn't see all of them' or 'saw none' — force the reading with no los vio a todos or no vio a nadie. Unclear pronouns: when two candidates share gender, a demonstrative picks the nearer one — cuando Marta llamó a Ana, esta estaba llorando means Ana was crying. &Be teaches this the way it actually gets used: talking, not worksheets — you hear the double reading, say both, and repair it aloud.
Below: the phrases that do the disambiguating, the clitic confusions (leísmo) that muddy who did what, and a way to practise the repairs in live spoken conversation.

Carla
Your grammar teacher for this pack
There are no drills here and nothing to fill in. In the Ambiguity Buster lessons, Carla feeds you sentences that can be parsed two ways and makes you say both readings before you fix them: she hands you a sentence with two feminine candidates and you rewrite it aloud for unambiguous reference; she gives you no vio a todos and you produce both paraphrases — saw none, didn't see all; she drops con el telescopio into a sentence and you repair the attachment three different ways. Spoken, in the moment, until spotting the double reading is a reflex.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.
Quick answers
A modifier that could attach to two different nouns: leí el libro del autor que me recomendaste — did you recommend the book or the author? A comma forces the far reading: leí el libro, del autor que me recomendaste. Moving the phrase also works: escuché con mis amigos la canción del cantante.
It's genuinely ambiguous — narrow scope ('didn't see all, saw some') or wide ('saw none'). Add a word to disambiguate: no los vio a todos for the partial reading, no vio a nadie for the total one. Compare no todos los empleados firmaron el contrato vs todos los empleados no firmaron el contrato.
A Juan le vi (leísmo de persona) is accepted in Spain but avoided in neutral Latin American Spanish, where the direct object is lo vi. The clear standard: le for the indirect object (le dije la verdad), lo/la for the direct (lo llamé pero no contestó).
Reintroduce the noun, or use a demonstrative — este picks the nearer candidate, so Pedro saludó a Luis antes de que este saliera means Luis left. Doubling the clitic also disambiguates: a ella le pregunté, no a él.
Plain o is usually inclusive: puede pagar con tarjeta o en efectivo — either or both. The doubled form forces exclusive: o aceptas la oferta o la rechazas, no hay punto medio. To insist either option is fine, add indistintamente.
