I have to admit there are many words I have a difficulty in creating a trick or mnemonic to help me remember them.
This device is a round-about trick. Someone may ask a “Penney for your thoughts” and I start conCENT-RATing really hard to say something that will be RATed as brilliant.
If you can come up with a better way to remember the spelling, please provide suggestions in the comment section of this blog. Thanks.
