Language can change meaning over time. Confusion can ensue.
For one example, see this week’s Odd Language.
There used to be a company whose name was sometimes written all in lower case as “viagrafix”. It was pronounced “via graphics”. These days, the first thought would likely be “viagra fix”. Just a little different!
If you say something and get looked at oddly by someone of a notably different age, it might just be that a meaning has shifted.
