when you use initial letters that don't spell another word ie as in acronyms. Initialisms seems such a mouthful - is it ok to still call them acronyms? I am thinking in terms of GHF (glass half full) which you cannot actually say easily.
BBC, ITV, Unesco and Nato are all abbreviations. The first two are initialisms, with the latter two being acronyms. So you can simply use 'abbreviation' unless you particularly need to make it clear that you're not referring to an acronym.
With all the mentions of the World Health Organisation during the pandemic, I wonder why it’s always pronounced W H O and not the Who. Or do they think we would we get it confused with the rock group?
there was a Terry Thomas comedy in 1961 called "A Matter of WHO". It was partly a comedy (about tracing a smallpox carrier), so they must have half-expected it to be proounced "who".
