Another pair of words that I frequently see misused is principle and principal…
Principle – a belief or moral that governs behaviour and decisions; a fundamental truth
On principle, John refused to watch the parade.
Principal – first or leading rank (e.g. a School Principal); initial sum of money before interest and fees
As Principal of the local school, Mary was well respected by the parents.
The most common uses of these words are often confused and used incorrectly. The easiest way to remember which is which is to think of your pal being a principal.
Here is a pair of words that sound exactly the same but have quite different meanings – yet I’m not sure any people realise there are two words instead of one with different uses.
discrete - distinct, separate, individual, referring to numbers
It was a series of discrete performances across the country.
discreet - tactful, subtle, unobtrusive
Her boss was very discreet about her illness.
To help remember which word is which, see how the t separates the es in discrete.
