Avvaiyar (Tamil: ஔவையார்; literally 'Respectable Woman') was the title of more than one female poet who were active during different periods of Tamil literature. They were some of the most famous and important female poets of the Tamil canon.
Abidhana Chintamani states that there were three female poets titled Avvaiyar. Among them, the first Avvaiyar lived during the Sangam period (c. 3rd century BCE) and is said to have had cordial relations with the Tamil chieftains Vēl Pāri and Athiyamān. She wrote 59 poems in the Puṟanāṉūṟu.
Avvaiyar II lived during the period of Kambar and Ottakoothar during the reign of the Chola dynasty in the tenth century. She is often imagined as an old and intelligent lady by Tamil people. Many poems and the Avvai Kural, comprising 310 kurals in 31 chapters, belong to this period.
The third Avvaiyar is the most widely known for her ‘Vinayagar Agaval’ ,‘Aathi Soodi’, ‘Kondrai Vendhan’, ‘Nalvazhi’ and ‘Moodhurai’.
The name Avvaiyar is a combination of Tamil word av vai with honorific suffix ar. Avvai refers to 'respectable elderly woman' as the word ammai which means 'good woman' in general term for a woman of any age. Thus the name Avvaiyar means a 'respectable good woman', hence a generic title rather than a specific name of a person. The word Auvaiyaar could also be a question as in 'who is that woman?' (Avvai meaning 'woman' and yaar meaning 'who').
The Avvaiyar who lived during the Sangam period is considered to be contemporary to poets Paranar, Kabilar and Thiruvalluvar. She is attributed as the author of 7 verses in Naṟṟiṇai, 15 in Kuṟuntokai, 4 in Akanaṉūṟu and 33 in Puṟanāṉūṟu. Legend states that she was a court poet of the rulers of the Tamil country. She travelled from one part of the country to another and from one village to another, sharing the gruel of the poor farmers and composing songs for their enjoyment. Most of her songs were about a small-time chieftain Vallal Athiyamaan Nedumaan Anji and his family. The chieftain had also used her as his ambassador to avert war with another neighbouring chieftain Thondaiman. The rest of her songs related to the various aspects of state governance. Although traditions claim that she was a sister of Kabilar, Thiruvalluvar and Athiyamaan, V. R. Ramachandra Dikshitar refutes this claim based on his studies that all four of them were most likely of different walks of life, thus from different caste backgrounds and hence impossible to be siblings. Tirukkovilur is an ancient temple town in Tamil Nadu. This is where the demon andhaka was killed by lord Shiva. Sangam epics recount that it was here that avvayar was blessed with a vision of her lord slaying andhaka and she has dedicated verses to the same. At great ancient temple of thillai chidambaram she sang Vinayakar Thiruakaval when lord Ganesha displayed his dancing form to her. Vinayakar Thiruakaval is an extremely esoteric work. 
View on Valluvar and the Kural
It is said that Avvaiyar was one of the several scholars who were present at the time when Valluvar submitted his masterpiece of the Tirukkural at the Madurai College. Soon after the presentation and the subsequent acceptance by the scholars and the Pandiyan King, Idaikkadar praised Valluvar and the Kural text thus:
The Cural contains much in a little compass. Such is the ingenuity of its author, that he has compressed within its narrow limits all the branches of knowledge, as if he had hollowed a mustard seed, and enclosed all the waters of the seven seas in it. [Emphasis in original]
On hearing this, Avvaiyar remarked to him that it would be more appropriate to liken the Kural text to an atom, which is even smaller than a mustard seed. Both Idaikaadar and Avvaiyar’s remarks appear as the last two verses of the Tiruvalluva Maalai.
The medieval period Avvaiyar was the court poet of the Chola monarch and was the contemporary of Kambar and Ottakkuttar. She found great happiness in the life of small children. Her works, Ātticcūṭi and Konraiventhan, written for young children, are even now generally read and enjoyed by them.
The following quotes from Aathichoodi illustrate the simplicity of her style and profoundness of the messages:

"Thol Ulagil Nallaar Oruvar Ularael Avar Poruttu Ellarkum Peiyum Mazhai" – The rain falls on behalf of the virtuous, benefitting everyone in the world.
"Nandri Oruvarukku Seithakkal An Nandri Endru tharum kol ena vaenda nindru Thalara valar thengu Thaanunda Neerai Thalaiyaalae Thaan Tharuthalal" -Don't wait for a return benefit as to when a good deed done will pay back, but be just like that tall and erect coconut tree that drank water from its feet gives the benefit of giving that sweet water by its head."
Her quote "கற்றது கைமண் அளவு, கல்லாதது உலகளவு" has been translated as "What you have learned is a mere handful; What you haven't learned is the size of the world" and exhibited at NASA. Her famous works include:
Annual Avvai Vizha is organised and conducted by the Government of Tamil Nadu to commemorate Avvaiyar's contribution to Tamil literature. This festival is celebrated every year in the month of Panguni on Sadhayam star day. Avvai Vizha has been started by local community long time back and still continuing willingly. Now Government of Tamil Nadu is continuing this function and adding more values. Local community, Tamil scholars and scholars from various fields participating with passion on this occasion and deliver their speech. Avvai Vizha is conducted in the temple Avvayar situated at Thulasiyappattinam village, Vedaranyam, Nagappatinam District, in the temple premises of Arulmigu Visvanathaswamy Thirukovil. Also this place is referred to famous interaction between Lord Muruga and Avvaiyar "Suttapazham Venduma Sudatha Pazham Venduma". This temple is under the control of the Hindu Religious and Charitable Endowments Department.
A popular legend in Tamil is the story of the first Avvaiyar and the Naaval (Jambu) tree. Avvaiyar, believing she had achieved everything that is to be achieved, was pondering her retirement from Tamil literary work while resting under a Naaval tree. She was then met by a disguised Murugan (regarded as one of the guardian deities of the Tamil language), who jousted with her wittily. He later revealed himself and made her realise that there was still a lot more to be done and learned. Following this awakening, Avvaiyar is believed to have undertaken a fresh set of literary works, targeted at children. These works, even after a millennium, are often among the very first literature that children are exposed to in Tamil Nadu schools.
Another legend has it that once the great king Athiyaman gave an "eternal" gooseberry (Nellikani in Tamil) fruit to Avvaiyar I. It was a special fruit that would bestow on whoever ate it a very long and healthy life. Athiyaman wanted Avvaiyar to eat the eternal fruit as she was the right person who could serve the Tamil community. If she could live forever, so would the Tamil heritage and language.
While on a visit to Ceylon, Avvai was caught up in a torrential rain, and took shelter in the house of two women of lower caste, Angavay and Sangavay. These women took care of Avvai with great kindness and the poet promised that they will be given in marriage to the King of Tirucovalur. On hearing this the King agreed to take the women in marriage if they were given away by the Chera, Chola and the Pandya kings. Avvai then makes an invocation to Ganesha for making the invitation on a palmyra leaf, on which Ganesha appears before her. On receiving the invitation the kings from the three kingdoms come to the wedding ceremony and give Angavay and Sangavay away in marriage. (pp.57-59).
