Language is always changing. At one point ‘an apron’ was ‘a napron’ while words like ‘literally’ are no longer literally literal. What are some language battles that have been lost in living memory and what are some others you predict will soon occur?
Edit: Non-english examples very welcome!
I don’t know if this fits the question, but in Brazil the “Portuguese-Language Orthographic Agreement of 1990” only started to take effect in 2009 (after I was born), in a transition state, and in 2015 it became official and obligatory.
The changes that I still fumble with are diacritics (e.g. “Idéia” -> “Ideia”) and hyphens (e.g. “contra-regra” -> “contrarregra”).
