This is a brief and simple theoretical explanation of relative clauses in English. In the last slide some links to exercises are included

2. RELATIVE PRONOUNS
• WHO refers to PEOPLE (a baker is a person who makes
bread)
• WHICH refers to OBJECTS (a pen is an object which is used
for writing)
• THAT refers to PEOPLE & OBJECTS (a baker is a
person that makes bread; a pen is an object that is used for
writing)
• WHOSE refers to POSSESSION (in Spanish "cuyo) (this is a
person whose house was destroyed by the earthquake)
• WHERE refers to PLACES (a bakery is the place where you
buy bread)
• WHEN refers to TIME (this is the day when I got married)

English)

3. DEFINING RELATIVE CLAUSES
• Son oraciones de relativo que añaden información esencial
sobre el antecedente
o This is the man WHO WON THE LOTTERY
o That is the bench WHERE I KISSED MY GIRLFRIEND
FOR THE FIRST TIME
• Si el pronombre relativo NO es el sujeto de la frase de
relativo se puede omitir
o The film (that) we like so much has won several awards
o The man (who) I met yesterday is my uncle

4. NON-DEFINING RELATIVE CLAUSES
• Añaden información no necesaria o esencial sobre el
antecendente
o Mariano Rajoy, who is the President of Spain, met Angela
Merkel yesterday
o Madrid, which is the capital of Spain, is situated in the
centre of the country
• La oración de relativo va siempre entre comas
• No se puede usar el pronombre relativo that
• No se puede omitir el pronombre relativo (en ningún caso)
