Ellie Simmonds, 4ft tall, is a British national treasure. In 2008, she captured the nation's heart when at the Beijing Paralympics she won two gold medals in the pool, at the age of 13. She has since won several more, gold, silver and bronze, in London and now in Rio. At the London games there was a wonderful moment when the Prime Minister, David Cameron (over 6ft tall) had to bend almost double to kiss her on both cheeks when he presented her with one of her medals.
Ellie suffers from achondroplasia, an inherited condition in which the growth of long bones by ossification of cartilage is retarded, resulting in very short limbs and sometimes a face which is small in relation to the skull (Oxford Dictionary Online)
The dictionary entry does not refer to dwarfism at all, and nor does the Wiki entry on Ellie Simmonds. But achondroplasia is such a mouthful of a word, and very few people know what it means, that it seems better to say she suffers from dwarfism.
Is there anything wrong with that?
