ELI5: Why is the english language so bad at describing weekly occurrences? (Next Tuesday and this Tuesday can mean the same or different things, biweekly means twice a week or every other week, etc.?)

Edit: I think all the argument in the thread below establishes that yes, this is indeed a confusing topic. My question remains why? Is there a linguistic explanation for gaps in a language that seem easy to fill with new, specific words but just aren't?

It is actually the opposite. In general there are accurate terms that change meaning as the popular use changes. English is a living language, and the meanings and use of words are constantly changing.

For example, Biweekly strictly meant every two weeks and was a replacement of fortnightly (first used in print in 1832). Some people were confused, understanding the 'Bi' meant two, and used it as a replacement for Semiweekly (first in print in 1890). The incorrect use of biweekly is so common now that English dictionaries list both definitions.

Starting with dictionaries printed in 2014, Merriam-Webster has now changed the definition of *Catfish* to include *a person who sets up a false personal profile on a social networking site for fraudulent or deceptive purposes*.
