alembic
Synonym discussion
Sense: noun/1
'Alembic', 'still', and 'retort' all belong to the language of distillation, but they differ in scope and tone. 'Still' is the broad modern term and can describe the whole setup used to heat and separate liquid. 'Alembic' is rarer, older, and often sounds literary or historical; it may point to a classical vessel and can also extend metaphorically to the refining of ideas or feelings. 'Retort' is narrower and usually names one vessel with a bent neck in older chemical equipment. A factory is more likely to install a still, a museum may display an alembic, and a historian may describe a retort in an early laboratory.
Etymology
Entered English through French and medieval Latin from Arabic al-inbiq, which itself came from Greek ambix, a word for a cup or still-head. The sense stayed close to distillation: first the vessel itself, and later, by metaphor, anything that seems to purify or transform thoughts and feelings.
