Etymology
The verb 'slog' emerged in the early 19th century, its origins obscure but strongly suggestive of onomatopoeic or expressive creation. It is thought to be an alteration or extension of the verb 'slug', meaning to strike heavily, influenced by the sound and feeling of a heavy, laborious blow. This auditory and sensory connection evolved logically into the modern senses of engaging in arduous, plodding work or movement, effectively transferring the concept of a heavy impact to the realm of sustained, wearying effort. Its journey reflects a classic pattern where a word coined to mimic a physical action broadens to describe a persistent and draining metaphorical struggle.
Analysis
The word 'slog' is a simplex word of uncertain origin, likely imitative or expressive in nature. It is not productively formed from distinct, separable morphemes in modern English.
