Tamils have strong attachment to the Tamil language, which is often venerated in literature as "Tamil̲an̲n̲ai", "the Tamil mother". It has historically been, and to large extent still is, central to the Tamil identity. Like the other languages of South India, it is unrelated to the Indo-European languages of northern India. The Tamil language preserves many features of Proto-Dravidian, though modern-day spoken Tamil in Tamil Nadu freely uses loanwords from Sanskrit and English and vice versa. Also, the language does not have many commonly used alphabets in the English language and Hindi (a product of Sanskrit and written in Devanagari script).
