* English's Foundation: English is a Germanic language, with roots in Old English (Anglo-Saxon). While it's borrowed heavily from Latin and Greek (especially in academic and scientific fields), those influences are largely in vocabulary, not grammar.
* Grammar Differences: Greek grammar is significantly different from English grammar. For example, Greek has grammatical cases (nominative, accusative, genitive, etc.) that English has mostly lost. Greek verbs have complex conjugations with multiple tenses and moods, while English verb conjugation is simpler.
* Historical Evolution: English's grammar has evolved over centuries, influenced by contact with other languages and natural language change. It's not possible to simply overlay Greek grammar onto English without causing major disruptions and making the language unintelligible.
Where Greek Roots Do Matter:
* Vocabulary: Many English words are derived from Greek roots. Understanding these roots can help with vocabulary building and word comprehension.
* Scientific and Academic Language: Fields like medicine, science, and philosophy have extensively borrowed from Greek. Knowing Greek roots can help decipher specialized terms.
A Hypothetical Scenario:
If you were to imagine a hypothetical language based on Greek roots, it would likely be a completely new language with its own rules of grammar and pronunciation. It would be a fascinating experiment in language creation, but it wouldn't be English.
In Summary: While Greek influences are present in English vocabulary, the core grammar of the language remains Germanic. It's not possible to base English grammar on Greek roots without fundamentally changing the language.
