Los colores representan los principales tipos de sintagmas:   |   Nominales   |   Verbales   |   Preposicionales   |   Adjetivales   |   Adverbiales   |   Las locomotoras representan el núcleo de cada sintagma:   |   sustantivo   |   verbo   |   sustantivo   |   adjetivo   |   adverbio   |

• Los pronombres posesivos, como los pronombres personales sujeto, siempre son el núcleo de un sintagma nominal que sólo tiene una palabra, porque sustituyen a un sintagma nominal completo (concretamente, a un adjetivo posesivo y un sustantivo: my house = mine).
  
  Excepto el primero, los demás son como los adjetivos posesivos, pero terminados en -s:
  
  

  Possessive adjectives				Possessive pronouns
  my	car	= [ mi coche]	____	mine	= [ (el) mío]
  your	son	= [ tu hijo]	____	yours	= [ (el) tuyo]
  his	idea	= [ su idea]	____	his	= [ (la) suya]
  her	plants	= [ sus plantas]	____	hers	= [ (las) suyas]
  its	legs	= [ sus patas]	____	its	= [ (las) suyas] (aunque no se suele usar "its" como pronombre)
  our	teacher	= [ nuestro/-a profesor/-a]	____	ours	= [ (el) nuestro / (la) nuestra]
  your	class	= [ vuestra clase]	____	yours	= [ (la) vuestra]
  their	house	= [ su casa]	____	theirs	= [ (la) suya]

  
  
• En inglés hay sólo un pronombre posesivo por cada pronombre personal, porque se refieren a la persona a la que pertenece un objeto o con la que tiene una relación (es pariente, amigo, profesor, vecino, etc.); en español hay muchos más porque los adjetivos posesivos se refieren a las cosas que se poseen o las personas con quienes se tiene una relación, así que distinguimos entre singular y plural, y entre masculino y femenino:
  
  

  mine =	(el) mío, (los) míos, (la) mía, (las) mías
  yours =	(el) tuyo, (los) tuyos, (la) tuya, (las) tuyas, + (el) suyo, (los) suyos, (la) suya, (las) suyas (de usted) + el / la / los / las de usted
  his =	(el) suyo, (los) suyos, (la) suya, (las) suyas + (el / la / los / las) de él
  hers =	(el) suyo, (los) suyos, (la) suya, (las) suyas + (el / la / los / las) de ella
  its	(no se suele usar)
  ours =	(el) nuestro, (los) nuestros, (la) nuestra, (las) nuestras
  yours =	(el) vuestro, (los) vuestros, (la) vuestra, (las) vuestras, + (el) suyo, (los) suyos, (la) suya, (las) suyas (de ustedes) + el / la / los / las de ustedes
  theirs =	(el) suyo, (los) suyos, (la) suya, (las) suyas + (el / la / los / las) de ellos / de ellas
