What does smoother mean?
“Smoother” most commonly means the comparative form of “smooth,” describing something that is less rough, uneven, harsh, or difficult. It may characterize a physical surface, such as a road or piece of timber, or describe movement and experience, as in a “smoother ride.” The word can also carry figurative meanings: a smoother process is better organized or less troubled, while smoother wording is more elegant and tactful. Less commonly, “smoother” is a noun for a tool used to finish or flatten a surface. This dual function is a useful example of how English derives both comparative adjectives and agent nouns with the suffix “-er.” In everyday speech, the noun is relatively rare, so context is important: “The surface is smoother” uses the word comparatively, whereas “Use a smoother” identifies a tool.
Less rough, irregular, or harsh; more even, polished, or comfortable.
"The new surface is smoother and easier to clean."
This is the comparative form of “smooth”; the superlative is “smoothest.”
A tool used to make a wooden, plastered, painted, or metal surface smooth and even.
"He drew the smoothing tool across the joint until it disappeared."
This sense is relatively uncommon outside contexts involving woodworking, plastering, or finishing work.
The plural is used when referring to more than one smoothing tool.
"The workshop has several smoothers for finishing different surfaces."
A smoother can mean the comparative of “smooth” or a tool that literally makes things smooth.

Where does smoother come from?
The word belongs to the family of “smooth,” which comes from Old English smōthe. Modern “smoother” is formed with the comparative suffix “-er” when it means more smooth, and with the agentive suffix “-er” when it names a tool that smooths a surface. The spelling with “th” reflects the historical influence of the voiced dental fricative of “smooth” on the suffix.
