What does bittersweet mean?
Bittersweet describes something that blends pleasure with sadness — an experience, memory, or feeling that is happy and painful at once. A graduation, a final goodbye, or a nostalgic song can all be called bittersweet: joyful in substance yet shadowed by loss or longing. The word also has literal senses. It can describe a taste that is both bitter and sweet, as in dark or semisweet chocolate, and as a noun it names Solanum dulcamara, a climbing plant with red berries whose flavour famously turns from bitter to sweet. English speakers have used the term since at least the sixteenth century, when it was applied to the plant before extending to feelings. Today its figurative use dominates: bittersweet has become the standard way to name life's complicated moments, those we cherish precisely because they carry both delight and ache. Its adverb and noun-of-quality forms — bittersweetly and bittersweetness — are rarer but well attested.
Giving pleasure mixed with sadness or pain; happy yet tinged with sorrow. Also, of food (especially chocolate): having a taste combining bitterness and sweetness.
"Their last summer together was bittersweet — full of laughter they knew would soon end."
The emotional sense is by far the most common in contemporary usage; the culinary sense applies chiefly to dark chocolate.
A woody climbing plant, Solanum dulcamara, of the nightshade family, with purple flowers and clusters of red berries; also called woody nightshade.
"Bittersweet scrambled over the garden wall, its scarlet berries bright against the autumn leaves."
Note that in North American usage 'bittersweet' can also refer to Celastrus scandens (American bittersweet), a different plant entirely.
Rare. The plural applies mainly to instances of the plant or to pieces of bittersweet chocolate.
"The hedgerow was tangled with bittersweets heavy with ripe berries."
Bittersweet is the only word that tastes exactly the way it sounds — literally, since it first named a plant whose berries flip from bitter to sweet on your tongue.

Etymology of bittersweet
Bittersweet is a straightforward compound of the native English words 'bitter' and 'sweet', both of Old Germanic origin. It was first applied to the plant Solanum dulcamara — named for the way its berries shift from bitter to sweet on the tongue — with this botanical sense attested by the mid-sixteenth century. The figurative sense describing mixed pleasure and sorrow developed later, becoming common by the eighteenth century and flourishing in modern usage. Because both elements are native Germanic roots shared across related languages such as German ('bitter' and 'süss'), close cognates exist throughout the Germanic family.
