Long words These pages are certainly not for the fainthearted! Starting with the longest words found in the new primary spelling lists for years 5 and 6 (words such as explanation and opportunity) we quickly move on to much longer words. Many children find long words fascinating and will enjoy exploring our page devoted to 15 letter words such as overfamiliarity and accomplishments. But, even better, we move on to 16 letter words before progressing to the longest words, some of which are very familiar, but not necessarily found in the dictionary. SUPERCALIFRAGILISTICEXPIALIDOCIOUS is a favourite, mainly because of the song by Mary Poppins and many children will be able to pronounce this, if not spell this 34 letter word. My personal favourite is FLOCCINAUCINIHILIPILIFICATION which has the wonderful meaning of the art of estimating as worthless! Our last page is devoted to two magnificently long words. The first has been published in the Oxford English dictionary and it means a lung disease caused by very small particles of fine volcanic ash. Medical and scientific terms can be elongated almost forever but this is one that has been generally accepted: PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS A superb 45 letters in length! Finally we come to our Welsh village: LLANFAIRPWLLGWYNGYLLGOGERYCHWYRNDROBWLLLLANTYSILIOGOGO-GOCH The name roughly translates as: The church of St. Mary in the hollow of white hazel near to the rapid whirlpool and church of St Tysilio of the red cave. Plenty of work can come from a study of this word, including research into where the village is and how the name came about. Well done to anyone who can spell this giant of a word!
