Several terms have come into vogue in the last few months which are chucked around with loose abandon.

"Pandemic": it's a pandemic if you are talking about the global situation. It's an epidemic if you're talking about the situation just in your own country: "The coronavirus epidemic in the UK is part of the global pandemic." You can't say "The pandemic in the UK has resulted in one of the world's worst death rates." But people do!

"Lockdown": an irritating word which doesn't convey anything about the restrictions in force.

"Social distancing": I have no idea why we need "social" in there...

"Jab": not descriptive of what the nurse or doc does at all.

"Self-isolating": just a really stupid expression.

"Covid": an unclever word used to make you sound clever. When I challenged someone who kept referring to "covid" he told me that "coronavirus" is too vague because there are lots of coronaviruses. I had to tell him that the ugly, confected word "covid" is merely short for "COronaVIrus Disease." There's nothing wrong with calling the current disease "coronavirus." It's a real word and everybody knows what it refers to in the current context. Likewise, "Covid-19." I asked my family in a Zoom last night what they thought it meant. Not one of them knew that the "19" stood for the year 2019. Just call the bloody thing coronavirus! And don't get me started on ridiculous constructions such as "pre-covid" and " post-covid"...
