The list opens with familiar words that end in O, each marked with a dot. Rarer words – plurals of unusual nouns, old forms and technical terms – join them when you switch Common words only off.
Use the length tabs for a word of a certain size, and the filter bar if you know how the word starts or what else it contains. Long lists are split into pages of 300. Every word you tap is copied and added to the copy panel at the bottom.
