It has come to my attention that although you have been attempting to use the English language some things seem to have gotten lost in translation somewhere over the Atlantic. So I just wanted to clear a few things up.
These are trousers
This is jam
Missing U – you seem to have dropped some letters over here, let me pick them up for you and put them back in a few words……. colour, flavour, humour, neighbour, favour, savour, glamour, rumour….etc
Wiggly red lines – When I spell optimise, criticise, ostracise, politicise, capitalise, dramatise, modernise, organise, rationalise,it is most definitely spelt with ‘ise’ NOT ‘ize’.
If you have any confusion about how to use the language correctly we have rather handily written a whole book about it. It’s called the Oxford English Dictionary. One could call it a definitive guide.
Setting the language -One last thing, THERE IS NO SUCH THING AS AMERICAN ENGLISH, it’s just English from England, the clue is in the name. Microsoft, the default setting is always English UK don’t be knobs!
