I knew citizens of the US used different words for a car mudguard, a bumper bar and a glove box. Pull the hood or bonnet. I knew they spelt colour as color. Wow, spell checker is not happy with color. I must have an English or Australian spell checker.
The battle with the great nieces of the Americanisation of our language is futile. No matter how many times old Aunty Andrew asks them to press the lift button, they will reply with, the elevator has arrived.
Over the years of blogging, differences I have learnt have really surprised me, such as the alt spelling of the word offence/offense. I was truly shocked at mould/mold. I had no idea. Now I wonder if in the US a mould or mold is used for a sculpture. I am reading a book set in India at the moment, a former English colony so I expected the spelling would be English English but it isn't. 'Wrong' spelling abruptly distracts me when I am reading.
This US couple produce quite good videos about their UK visit. They remark about the differences between the two countries without criticism. Their enthusiasm is infectious. https://www.youtube.com/@TheMagicGeekdom Apparently in the US mediaeval is a three syllable word whereas some of us will know it as a four syllable word. She can't pronounce the word with four syllables.
But we are not slavishly tied to the UK. We say zucchini as is used in the US, not courgette. We say eggplant not aubergine.
I am not sure any Australian knows the difference between rock melon and a cantaloupe. Is there a difference? Do educate me.
