I have three main pet hates in the english language - 'got', 'of', and 'di-sect'.
'Got' is a weed, which worms its way into the cracks in the language. The only valid use of 'got' is as past tense of 'to get'. It has for a very long time become an indication of necessity, as in "I have got to go to the bank". Leaving out 'got' results in "I have to go to the bank", which means exactly the same as the previous attempt. If more urgency is required, try "I must go to the bank".
I blame the Specsavers advertising campaign for the corruption of 'should have' to 'should've', which by back formation has become 'should of'. Several younger members of my family, plus assorted uneducated friends, use 'of' in place of 'have' at all opportunities - 'could of', 'should of', 'would of', 'might of', etc. etc., ad nauseam. I became so incensed some time ago that I even wrote to Specsavers to ask them to desist and have their adverts rerecorded using the proper term 'should have'. They declined for some inexplicable reason.
Where did that abomination 'di-sect' come from? The word is 'dissect', with two esses. Other double ess words do not appear to have been similarly bastardised - dissociate, dissemble, dissent, etc., so why has dissect been selected for this treatment? Many a TV police drama series has been ruined by the Medical Examiner (Yes, you, Ducky) saying that he was going to 'di-sect' the body that has been placed on his table. GRRRRRR!!!!!!
But my overwhelming all time hate is the use of the term 'Engineer' to describe a technician, who definitely does not have the qualifications to use that moniker. The latest offering from British Gas (ptooi!) says that they have 6000 'Engineers' waiting to service your gas appliance. NO they haven't. They may well have 6000 trained gas fitters, but not one of them has a BSc., BA., or other higher education qualification. I am afraid that an NVQ in Gas Fitting does not qualify them to call themselves 'Engineers' Honestly, the country is going to the dogs.
