The word "ugly" is often used to describe something unattractive or displeasing to the eye. However, there are plenty of alternative synonyms for the word. For example, "unappealing" or "unsightly" can convey a similar sentiment without being quite as harsh. "Repulsive" and "disgusting" are also options that carry a bit more weight. If you're looking for a more subtle way to describe something that's less than beautiful, you might choose words like "plain," "unremarkable," or "forgettable." Ultimately, the synonym you choose will depend on the tone and context of your writing or conversation.
