Your Fix
Learn words in chunks so you have a better idea of how a vocabulary word is functioning in context.
Going further, you may want to consider switching from a dictionary that translates your native language to your target language to one entirely in your target language. This will give you insight into how the natives themselves would describe the multiple uses of the word.
You can find many of these online for free. For example, WordReference offers definitions in Italian, Spanish and English. You can also simply search “{target language} dictionary” in the foreign language you’re learning.
