The Japanese adjective '悲しい (かなしい)' means 'sad'. It is used to describe a feeling of sorrow, unhappiness, or grief. This word can be applied to situations, events, or personal emotions. For example: I feel sad「私は悲しい」(わたしはかなしい). That movie was sad「その映画は悲しかった」(そのえいがはかなしかった). It can also be used to describe something that evokes sadness, such as a sad story「悲しい話」(かなしいはなし). The nuance of '悲しい' often implies a deeper, more emotional sadness compared to other words like '寂しい (さびしい)', which can mean 'lonely' or 'lonesome'.
