I am very confused in the correct usage of 'had had / has had / had'. Can somone please explain me the usage or pointers to some text for this.
In simple words:
has/have had-- first "has/have" is indicator of present prefect tense. While second "had" denotes possession.
for e.g."I HAVE HAD enough of you!". In this sentence you are still angry , I mean at the time of writing this sentence your were angry,So present perfect is used. (Present Perfect indicates either 'continued action or continued effect of a completed action. )
had had--here first "had" is indicator of past prefect tense & second "had" denotes possession.
for e.g. He said he had had a family before he got homeless.
Another one: "I had had a girlfriend before her", here, it means you had 2 girlfriends before your present girlfriend, 1st girlfriend broke up, and then here comes the 2nd, and finally your present girlfriend.
