Udvid was one of the eight thousand names of Śiva (Siva). The commentator Nīlkaṇtha (Nilkantha) also analysed the meaning of the name, Udvid in this way- Udvit udvidyāvirbhavatīti vā phalam udvinattīti vā sthāvararūpo vā. In Saṇskṛt (Sanskrit), the verb ‘bhid’ means to come out. Something which comes out of the soil- in this context, Udvid means trees (Ud+Bhid+kvip). Vṛkṣa (Vriksha or trees), Gulma (Plants), Tṛṇa (Trina or grass), Vallī (Valli or creepers) and Latā (Lata or climbers)- these are the five types of Udvid which can be found in nature. Śiva (Siva) was named as Udvid as he was imagined as the Lord of all these Vṛkṣas (Vrikshas or trees) and Oṣadhis (Oshadhis or medicinal plants). Similarly, in the Śivasahasranāma Stotra (Sivasahasranama Stotra or a hymn chanting the thousand names of Lord Siva), many times Lord Śiva (Siva) was called as Mahouṣadha (Mahousadha) and he was also imagined as many types of Vṛkṣas (Vrikshas or trees) such as Vakula, Candana (Chandana or Sandal), Chhada etc. For this reason, Udvid was one of the natural names of Mahādeva (Mahadeva).

Secondly, the commentator Nīlkaṇtha (Nilkantha) also analysed the meaning of the name, Udvid in another way-
Śivamahādeva (Sivamahadeva) was himself the epitome of yajña (yajna).

He said this, because Śiva (Siva) came out of the Vedic ritualistic performances to bestow the blessed fruit of the yajña (yajna). Śiva (Siva) epitomized the outcome of all the good and bad deeds of human beings. He brought in the result out of human actions. As Śiva (Siva) manifested the fruit of the actions accordingly, he was also famous as Udvid.
