"تلخ" is an Arabic word that translates to "bitter" in English. It is often used to describe the taste of certain foods and drinks, such as قهوة (coffee) or شوكولاتة (chocolate) that have a strong, sharp flavor. The term can also refer to experiences or feelings that are unpleasant or difficult to endure. In a broader context, "تلخ" can symbolize emotional states, such as sadness or disappointment. For example, a person might describe a difficult life event as "تلخ," indicating that it left a negative impact on their feelings. This dual meaning highlights how taste and emotions can be interconnected in language.
