(SOURCE) One of the many fascinating features of our language is how often words with pleasant associations are also quite pleasing on the tongue and even to the eye, and how many words, by contrast, acoustically and visually corroborate their disagreeable nature — look no further than the heading for this post. Enrich the poetry of your prose by applying words that provide precise connotation while also evoking emotional responses. (Note the proportion of beautiful words to ugly ones in the compilation below; it’s easier to conjure the former than the latter, though I omitted words associated with bodily functions, as well as onomatopoeic terms.) Notice how often attractive words present themselves to define other beautiful ones, and note also how many of them are interrelated, and what kind of sensations, impressions, and emotions they have in common. Also, try enunciating beautiful words as if they were ugly, or vice versa. Are their sounds suggestive of their quality, or does their meaning wholly determine their effect on us?
