ELI5 : How come most people who lost their memories but never forget their language vocabulary?

Speech and memory are controlled by different areas of the brain. The hippocampus is located in the brain's temporal lobe and is involved with the formation of memory, while Broca's area in the left hemisphere is involved with language. Depending on what caused the amnesia, the speech region can remain unaffected and allow the amnesiac to still speak.
