The name Ṣughdī ibn Sinān requires attention to consonants and vocalization. Other similar-looking names occur, so an unfamiliar form should not automatically be equated with the better-known name of a different transmitter.
Sindar, the client of Zinbāʿ al-Judhāmī, illustrates a distinctive recorded name whose form should not be silently normalized into a common word. Such alterations can compromise identification.
For an ism mufrad, unusual appearance alone is insufficient. Its correct reading, attribution to a particular bearer, and distinction from persons with similar names must be established through chains and biographical evidence.
