Thinner, the term that describes a reduction in size or quantity, can be replaced by a myriad of synonyms. Some of these include leaner, slimmer, slighter, skinnier, trimmer, and lighter. These words help to communicate a range of meanings that differ only slightly, but can still affect the overall message of a sentence or paragraph. Synonyms can enhance a writer's vocabulary and offer a more nuanced way to convey the intended message. The ability to use different words for the same meaning adds depth to language and enriches the reader's experience. It's always good practice to incorporate synonyms into your writing and to choose the best term that suits your context.
