In Hermopolis, Thoth led "the Ogdoad", a pantheon of eight principal deities, and his spouse was Nehmetawy. He also had numerous shrines in other cities.
Thoth played many vital and prominent roles in Egyptian mythology, such as maintaining the universe, and being one of the two deities (the other being Maat) who stood on either side of Ra's solar barge. In the later history of ancient Egypt, Thoth became heavily associated with the arbitration of godly disputes, the arts of magic, the system of writing, the development of science, and the judgment of the dead.
The Egyptian pronunciation of ḏḥwty is not fully known, but may be reconstructed as *ḏiḥautī, perhaps pronounced *[t͡ʃʼi.ˈħau.tʰiː] or *[ci.ˈħau.tʰiː]. This reconstruction is based on the Ancient Greek borrowing Thōth (Θώθ[tʰɔːtʰ]) or Theut and the fact that the name was transliterated into Sahidic Coptic variously as ⲑⲟⲟⲩⲧThoout, ⲑⲱⲑThōth, ⲑⲟⲟⲧThoot, ⲑⲁⲩⲧThaut, as well as Bohairic CopticⲑⲱⲟⲩⲧThōout. These spellings reflect known sound changes from earlier Egyptian such as the loss of ḏ palatalization and merger of ḥ with h i.e. initial ḏḥ > th > tʰ. The loss of pre-Coptic final y/j is also common. Following Egyptological convention, which eschews vowel reconstruction, the consonant skeleton ḏḥwty would be rendered "Djehuti" and the god is sometimes found under this name. However, the Greek form "Thoth" is more common.
According to Theodor Hopfner, Thoth's Egyptian name written as ḏḥwty originated from ḏḥw, claimed to be the oldest known name for the ibis, normally written as hbj. The addition of -ty denotes that he possessed the attributes of the ibis. Hence Thoth's name would mean "He who is like the ibis", according to this interpretation.
Other forms of the name ḏḥwty using older transcriptions include Jehuti, Jehuty, Tahuti, Tehuti, Zehuti, Techu, or Tetu. Multiple titles for Thoth, similar to the pharaonic titulary, are also known, including A, Sheps, Lord of Khemennu, Asten, Khenti, Mehi, Hab, and A'an.
In addition, Thoth was also known by specific aspects of himself, for instance the moon god Iah-Djehuty (j3ḥ-ḏḥw.ty), representing the Moon for the entire month.
The Greeks related Thoth to their god Hermes due to his similar attributes and functions.
One of Thoth's titles, "Thrice great" was translated to the Greek τρισμέγιστος (trismégistos), making Hermes Trismegistus.
