Etymology

The word "simmer" likely originates from the imitative sound of gentle bubbling ("sim-"), combined with the frequentative verb suffix "-er" (indicating repeated or ongoing action). First recorded in the mid-17th century, it reflects the auditory experience of liquids cooking just below boiling point. The onomatopoeic quality makes it memorable and logically connected to its culinary meaning.
