Etymology
the word 'chug' is a modern english onomatopoeic creation, first recorded in the late 19th century, designed to imitate the short, dull, explosive sound of a steam engine or a similar rhythmic, laborious noise. it is part of a rich tradition of sound-imitating words in english, like 'thump' or 'clang', which are formed based on auditory perception rather than classical roots. from this core meaning of a repetitive sound, the verb naturally extended to describe the action of drinking quickly, evoking the sound of liquid being gulped down in a continuous series. as such, 'chugging' represents a direct sensory metaphor, where an action is named for the characteristic sound it produces.
Analysis
the word 'chugging' is an onomatopoeic formation based on the simplex root 'chug', which imitates a repetitive, dull, explosive sound. the suffix '-ing' is added to form the present participle or gerund.
