In Hindu astrology, Kṛttikā is the third of the 27 nakṣatras. It is ruled by Sun.
Under the traditional Hindu principle of naming individuals according to their Ascendant/Lagna nakṣatra, the following Sanskrit syllables correspond with this nakṣatra, and would belong at the beginning of the first name of an individual born under it: A (अ), I (ई), U (उ) and E (ए).
