Before you choose
Compare the lookup tools you need
The comparison covers audio pronunciation, usage examples, translation lookup, offline access, mobile apps and languages covered. Match those fields to the way you plan to look up words.
A dictionary focused on medical terms may suit a different task from a general dictionary or a Chinese dictionary.
Check free access and paid entry points
Pricing labels include free, freemium and paid plans. MDBG Chinese Dictionary lists a free plan with paid access from $15.95, while Pleco Chinese Dictionary lists paid access from $4.99.
Trial periods vary. Oxford Learner’s Dictionaries lists three days, ABBYY Lingvo lists 15 days and dict.cc lists seven days.
Choose platforms that fit your devices
The listed platform labels include web, Android, iOS, macOS, Windows and API access. Check the platform field before choosing a dictionary for a phone, computer or software project.
Mobile apps and offline access are separate comparison fields, so a service with an app may still require an online connection for some lookups.
Match the dictionary to your language work
Use the languages-covered and translation-lookup fields when you work across languages. Names such as MDBG Chinese Dictionary, Pleco Chinese Dictionary and Linguee indicate different lookup focuses to compare.
For specialist terms, Merriam-Webster Medical Dictionary is listed alongside general dictionaries.
