Colour is spelt with a 'u', Aluminium has 5 syllables, and Encyclopaedia does indeed have an 'a' in it. In addition, sulphur is not spelt with a 'f', foetus has an 'o', and 'organisation' is indeed spelt with an 's', as are many other words you spell with a 'z' (which is incidentally a 'zed', not a 'zee'), and it's "spelt," not "spelled." And if you can't use apostrophes correctly, *learn*. It's not hard. Plurals don't need them, normal possessives do, contractions do, 'its' as a posessive doesn't. Thank you.
