Spelling Tip – of all the sion/tion words this is easy to remember as a member of the ‘sion’ family simple because the ‘tion’ would make it “o+ ccat + ion” when we say it - and it sounds so wrong! So to help you with this spelling say - "On this occasion, there is no ‘cat’ to complain about!"
o + cc + a + sion
Use the word as many times throughout the week as you can. This can be verbally, in your written work or listen out for other people using it.
