What does 'form' refer to in language?

The term 'form' in language refers to the way a word is spelled, pronounced, or inflected. This encompasses various aspects of language, including grammar and morphology, which involves how words are constructed and how their shapes change depending on their use in sentences. For instance, the form of a verb may change based on tense, such as 'run' changing to 'ran.' Additionally, the pronunciation of a word can affect its meaning or its usage in different contexts, highlighting how form is a foundational element in understanding and using language effectively. This concept is crucial for grasping how words function within a language and communication overall.
