@MyrtleLion root words uncover other root words and singular words uncover multiples. Eg "be" will also uncover is, was, were, being etc. "it" uncovers they, he, she, its.
If you tap a blank word, the word length is shown in the blank space.
There are often formatting clues, brackets at the start with a colon after the first word show a translation, if the pre-colon word is 5 letters it's often Greek or Latin. If the words in the bracket are the pattern (XX XXXXX XXXX-XX XXXXXX XXXX) the bracketed words are usually birth and death dates so you're looking for a person.
