Comprehensive
For example, when someone suggests something, I often say "prefect" as in let's do it, good plan. But my serbian boyfriend suggested the translation of excellent instead. With this dictionary translation I can see why they wouldn't apply the word prefect in that way (commonly). Also, looking up the translation for "How old are you?" tells me it means how many years do you have? I've found this to be more helpful than simply google translate.
Thank you, I appreciate the resource!
