Episodic Memory holds the past, and Language Memory holds the key to tell it.
We all have heard accounts of amnesia victims who have lost all memory of their past. They don't know where they were born and raised, or even where they live now.
Strikingly, what they have not lost is their knowledge of the world around them (semantic memory), nor their language to express all their confusion.
Language Memory: A person with amnesia can’t recall the past but can discuss it with no problem. A person with a language problem, on the other hand, can remember the past but can’t recall his/language to talk about it.
This, as we have discussed earlier, is called aphasia. Of course, Language memory itself isn't a single separate entity either.
