sense
The Italian word 'senso' is largely used similarly to English 'sense', as it can refer to one of the five senses (i.e., sight, hearing, taste, smell, touch), as well as to mean meaning or significance (as in, 'What is the sense of this word?'). However, remember that as with all translations, there can be exceptions and non-literal uses in various contexts.
