"sensible" is a "faux-ami", it does not translate directly : in English, "sensible" means reasonable or relevant.

There are other faux-amis, ie words which are similar or look close but don't mean what they look:

• "deceiving" is not "décevant" (disappointing) but "trompeur"
• "actually" is not "actuellement" (currently) but "véritablement"

Used to have a similar meaning in English. Always helps me to remember Sense and Sensibility. The younger sister is sensitive rather than sensible!

sensible (well-advised, wise) = sensé(e), raisonnable
