The literal meaning is equivalent in English to "having guts", and the word derives from sisus, which means something inner or interior. However sisu is defined by a long-term element in it; it is not momentary courage, but the ability to sustain an action against the odds. Deciding on a course of action and the sticking to that decision against repeated failures is sisu. The noun sisu is related to the adjective sisukas, one having the quality of sisu.
