👉 The term "fluid" in the context of exceptions typically refers to elements within a language, such as grammar rules or linguistic structures, that deviate from the standard or expected norms. These exceptions can arise from various sources, including regional dialects, historical linguistic changes, or specific contexts where the general rule no longer applies. For instance, in English, the verb "to be" is an exception to the typical pattern of forming past tense verbs like "walked" or "jumped," which follow the -ed rule. Similarly, in grammar, certain prepositions or conjunctions might have exceptions to standard usage, such as "but" preceding a clause that starts with a vowel sound. These exceptions highlight the dynamic and sometimes unpredictable nature of language, reflecting its evolution over time and its adaptability to different contexts.
