Historical forms of the character 於
Western Zhou	Warring States	Liushutong (compiled in Ming)
Bronze inscriptions	Chu slip and silk script	Transcribed ancient scripts

From an ancient variant form of 烏. Not related to 方 or 㫃.

From Proto-Sino-Tibetan *ʔaj (“to go; directional particle”) (Schuessler, 2007). It has slowly replaced the older 于 (OC *ɢʷa) (ibid.). This etymology is incomplete. You can help Wiktionary by elaborating on the origins of this term.

In Mandarin, this is innovatively pronounced yú. Schuessler (2007) see this pronunciation from 于, essentially treating this phonomenon a xundu (訓讀／训读). While Sun (2018) see this innovative pronunciation developed phonetically.
