The word is an adjectival form of the Sanskrit word diksha, meaning provider of knowledge. Dikshita in Sanskrit derives itself as a person involved in scientific studies, and literally translates as "one who has received initiation or one who is initiated". Historically, the surname has been usually associated with professions related to knowledge, generally used among teachers and scholars. The word dixit means the one who has been initiated. The Dikshit/Dixit surname is usually associated with Hindu Brahmins in India especially in Northern India and Nepal.
In the ancient days, Brahmins were associated with the rituals and Vedic Yajnas, and performed the same. Since these rituals were much complicated affairs, and needed a vast study of religious texts, they had to spend seven years or more on this vocation to specialise. Thus derived their family names. Dixit Brahmins are residing in the Uttar Pradesh, Uttrakhand, Punjab, Haryana, Madhya Pradesh, Jharkhand, Bihar and many of them belong to “Kaanya Kubja” lineage, some are there in Maharashtra also.
There were some who were initiated to perform long Yajnas, one-year, two-year or even many-year-long Yajnas; they were initiated into the same, and had to undergo the rules for the entire period. Hence, to differentiate them from others, they were called as dixit, or the initiated, so that they do not indulge in other worldly affairs, and devote their time to the Yajnas they were committed to.
It is the same with the Vajpayee Brahmins, who excelled in performing Vajpeya, a shraut Yajna. There are some Brahmins with the surname of “Soma Yaaji” or those, who performed the Soma Yajna. There is one such title of “Yajwaa”, the one who performs the Yajna.
The most common such title is the “Agnihotri “, one who performs the daily rituals of offering to Fire God. There are Brahmins with the title “Hotaa”, who belonged to the tradition of Rigveda, in the Yajnas. Then there are Satpathy, who relied on the Shatpatha Brahamana. The word is an adjective form of the Sanskrit word diksha, meaning provider of knowledge. Dikshit in Sanskrit derives itself as a person involved in scientific studies, and literally translates as "one who has received initiation or one who is initiated".
 In the southern state of Tamil Nadu, the famous Nataraja temple of Chidambaram is managed and administered hereditarily by a class of Vaidika Brahmins called Chidambaram Dikshitar whom, legends say, were brought here, from Mt. Kailasha, by Maharshi Patanjali, specifically for the performance of the daily rituals and maintenance of the great temple of Chidambaram.
