Neither did I.
I simply bought a cheap book on it from W H Smith's and tried to get a sort of understanding of how - when you see a Latin word - the English word suddenly makes sense.
For instance the word for 'water' in Latin is 'Aqua'.
So you start to understand why we keep fish in an AQUArium, or the star sign of the water carrier is AQUArius, etc.
Or 'Dexter' is the Latin word for 'right' - most people are right handed - so a person who can use both hands equally as well are known as an ambiDEXTER (or someone with two right hands!).
I know - I need to get out a lot more!

Bob - Don't let the bastards grind you down!
