These are some mnemonics for words that begin with the alphabets beginning with - 'b', 'c' and 'd'.

I know this is particularly difficult in English as many words are derived from the languages of the various conquerors of the British Isles, the Saxons, the Vikings, the Angles (yes, there were a people called that and I'm not sure if they were very geometric!😀), the Normans, the Romans and that is why you will often find several words that mean the same thing.
