Whether you’re working for that star client, doing a crossword, writing a special CV cover letter or sitting an exam, it’s essential to find the right word. That’s where a thesaurus comes in. But with so many options to choose from, what’s the best thesaurus to use? We’ve done the research for you. So, if you’re wondering which is the most suitable thesaurus for your needs, read on.

How do you choose a thesaurus?

Here are some important things to consider when you choose a thesaurus:

1. Date of the most recent edition. The English language is constantly evolving. The more recent the thesaurus edition, the more relevant it’s likely to be to your needs.

2. Number of entries. This will have a big impact on price. If you’re a professional translator or writer, it’ll be worth investing in a more comprehensive thesaurus. If you’re a student or want to add a thesaurus to your bookshelf at home to help with crosswords, a smaller one will probably do the job.

3. Synonyms and antonyms. The inclusion of antonyms is a useful feature for writers. But it’ll probably increase the size and cost of the thesaurus so consider whether or not you’re going to use them.

4. Target audience. Some thesauruses are specially designed for English language learners. Others are more suited to speakers of American English. Look for one created to fulfil your needs.

5. Features. Certain thesauruses include example phrases, definitions, Latin phrases, special sections for vocabulary building and additional online materials. Perhaps those features matter to you and perhaps they don’t. This can affect how much you spend.

If you’re a translator planning to sit the DipTrans exam, you can only use paper resources. We highly recommend including a thesaurus among your resources as it can come in handy in all parts of the exam.

Conclusion on which is the best thesaurus for writers and translators in 2023

Scroll down for more information on each of the thesauruses researched. But if you’re impatient to find out the winner, here are our recommendations.

Best thesaurus for writers and translators 2023: Oxford American Writer’s Thesaurus. Having been updated in 2012, the layout and additional information included in this book make it a very attractive option as the best thesaurus for writers and translators. I bought it even though I write in UK English and I love it.

BUT, if you’re outside the US and the shipping cost is too high or if you want UK English, our second choice is the Oxford Thesaurus of English because it’s the most comprehensive option.

Best choice for the home bookshelf: Collins English Thesaurus Paperback. Recently updated and with plenty of content for your average user.
