Feeling blue
English Idiom
Meaning: Experiencing a state of sadness or melancholy, often without a specific reason. This phrase describes a mood where someone feels down or dispirited.
Origin: The idiom 'feeling blue' originates from the old nautical custom where if a ship lost its captain or any important crew member, the ship would fly blue flags and paint a blue band around the ship as a mark of mourning. Over time, this tradition evolved into the phrase we use today to describe a feeling of sadness.
