Mnemonics

Mnemonics
are techniques or tricks to aid memory. One well-known to those who have had
piano lessons is ‘Every Good Boy Deserves Fruit’ for the notes on the lines of
the treble clef – E, G, B, D, F. To remember the spaces of the bass clef, A, C,
E, G, the mnemonic is ‘All Cows Eat Grass’.
Mnemonics
take many forms. For children it may be a song to learn the alphabet, for
example, or an acronym in sentence form to remember the colours of the rainbow –
Richard Of York Gave Battle In Vain. It might be a word – HOMES, to recall the
names of the North American Great Lakes – Huron, Ontario, Michigan, Erie.
Superior.
It could
be a list, like ‘divorced, beheaded, died, divorced, beheaded, survived’ to
remember the fate of Henry VIII’s six wives.
Can’t
remember how many days there are in each month? There’s a rhyme to help.
Thirty days
hath September,
April,
June and November,
All the rest
have thirty-one
Except for
February alone,
And that has
twenty-eight days clear,
And twenty-nine
in each leap year.
I’ve just
learnt a new mnemonic, which is easier and involves the knuckles of the hand.
Starting with the left hand and the first fist knuckle, January (31 days), depression
between the knuckles, February (not 31 or 30 days, so has to be remembered
along with the leap year bit!), second knuckle, March (31), second depression,
April, (30) and so on across the knuckles. Of course, there is a spare
depression and knuckle at the end!
Spelling
can often be helped with a mnemonic – ‘Big Elephants Can’t Always Use Small Elevators’
spells ‘because’, or, a particular favourite from the film ‘Matilda’ – ‘Mrs D,
Mrs I, Mrs F, F, I, Mrs C, Mrs U, Mrs L, T, Y.’
A
mnemonic might be a little rhyme to aid spelling – ‘i before e, except after c’,
although there are many exceptions to that rule. Sometimes, the first part
is followed by, ‘Or when sounded as ‘a’, as in neighbour and weigh’.
A mnemonic
can help in distinguishing homophones – is it here or hear? ‘I hear with my ear’.
Should it be which or witch? ‘The witch had an itch.’
Once past
primary age and into secondary school and beyond, mnemonics take on a wider-ranging
cast, in electrical engineering, geology, physics, chemistry, foreign languages
– it seems that many disciplines benefit from an aide-memoire. Are they
necessary (one collar, two sleeves) or
superfluous?
