Greek Grammar refers to the set of rules that govern the structure and use of the Greek language. It includes aspects such as syntax, morphology, and phonetics, which help in understanding how words are formed and combined to create meaningful sentences. One key feature of Greek Grammar is its use of cases, which indicate the role of a noun in a sentence, such as subject, object, or possession. Additionally, verbs in Greek are conjugated to reflect tense, mood, and voice, making the language rich and expressive.
