Notes

A dictionary is a useful, but not an all-important tool in your language-learning arsenal. Why? Simply because a language dictionary does not give you context that will help you better understand a language and gain fluency. It's much better to understand the context instead of just looking up the definition.
Finding words in a print dictionary or thesaurus exercises kids' minds and helps them develop their problem-solving skills. To find a word, they have to consider order and sequencing, alphabetization, spelling, context, and much more! Faster isn't always better when it comes to literacy and learning
Reading the dictionary is actually one of the best ways to improve your vocabulary. This is why most language experts will advise you to read books as well as use the dictionary to find the meaning of words that you don't understand.
Hence, we can conclude that checking the passive voice of a word is the least important about the use of a dictionary.
