Relatives & Prepositions
Informal vs Formal. Do you drag the preposition at the end, or do you move it to the VIP front seat? Informal vs Formal. ¿Arrastras la preposición al final o la pones en el asiento VIP delantero?

The Logic of
Relative Clauses
No estudies reglas, estudia conexiones. Aprende a usar el "pegamento" (Who, Which, That) para unir ideas complejas.
"The man WHO called me..."
Choose your "Glue"
Dependiendo de a qué te refieras, necesitas un "pegamento" distinto. Haz clic para escuchar.
Neuro Tip: Hooks
Imagina que los pronombres son "ganchos" (). La primera frase tiene un objeto, y el pronombre "engancha" la información extra a ese objeto.
¡Cuidado con WHOSE!
Whose sustituye a "My, Your, His, Her, Its, Our, Their".
"I met a man. His car was gold."
↓
"I met a man WHOSE car was gold."
The Comma Logic
¿Pongo comas o no? Todo depende de si la información es vital o "cotilleo".
Essential Info
Sin comas. Si lo quitas, la frase no se entiende.
"The man who called me is here."
- Define exactamente quién es.
- NO COMMAS.
- Puedes usar THAT.
Extra "Gossip"
Con comas. Si lo quitas, la frase sigue teniendo sentido.
"My boss , who called me , is angry."
,- Añade info extra (sabemos quién es "My boss").
- COMMAS = Pausas para respirar.
- NEVER use THAT.
The Ghost Rule (Omission)
A veces, el pronombre puede desaparecer como un fantasma. Haz clic para escuchar y ver la magia.
The Rule: Object Pronoun
Solo puedes quitar Who/Which/That si va seguido inmediatamente de un SUJETO (I, You, He, The man...).
The book that I read.
The book that is on the table.
