Very refined form of call quality to join (in our language, almost exclusively) the edges of the eyelids or lips. It comes from the latin com ("joint"), my (derived from the verbal form mittere, "put, place in a location") and the suffix _idad, indicating a quality. I never understood how words like 'corner' (of similar etymology to the so-called 'comisidad') was completed by associating with skin folds. I almost prefer to believe that they wanted to ask about comedy, and not make me more problems.
comisidad is incorrectly written, and should be written as "humour" being its meaning:
Abstract quality of the comic from the Greek komikos komike komikon: with regard to comedy and komos komou: party with music and dance in honor of the God Dionysus (Baco ). For us the comic is that produces laughter and fun.
