For example, switching out the word ‘boot’ for ‘trunk’, or ditching the word ‘rubbish’ for ‘garbage’.
This is something I’ve noticed my 6 year old does pretty regularly. We went through a stage where ‘sweets’ became ‘candy’, ‘holiday’ became ‘vacation’ and ‘courgette’ became ‘zucchini’.
That last one didn’t happen but if you’re still reading you’ve got my respect, or as the Americans might say ‘…mad props’.
I’m partial to ‘wankspanner’. Which is pretty un-American since even if they knew what to wank meant, they’d probably to with ‘wankwrench’ which just isn’t the same. Sorry, I’m moving into rambling territory now.
