For a very, very long time I thought several meant exactly seven. I also wondered why there weren't corresponding words for the other numbers.
I believe it did at one point.
Probably most of the confusion over the numeral value (or lack thereof) for terms like 'couple', 'several', is due to them being popularly being misused. It used to mean a specific amount, and now it conventionally doesn't.
Wouldn't be surprised if future generations are utterly confused over any utterance of the word "literally" because it could mean that it did or didn't actually happen.
