E16 has Tingal [tie] as a separate language. This division stems from a conservative interpretation of Tucker, Archibald N. and Bryan, Margaret A. 1966: 70 's rendering of information provided by Stevenson. Stevenson had no first-hand data from Tingal and therefore could not assert that Tingal was a either a separate language or a dialect of Tegali or of Tagoi ( Stevenson, Roland C. 1956/1957: 103 ). When an early version of the Ethnologue was compiled, such cases were rendered as separate languages, and while some others, such as Tukum and Turum, were weeded out later, Tingal remained (p.c. Andrew Persson 2009). In July 2009 in Kadugli, I was able to find a speaker who had grown up in Tingal and had excellent command of the language. While I only had the opportunity to spend an hour or so with him, his speech was nearly identical to the Rashad and Tegali [ras] materials in Stevenson, Roland C. 1956/1957: 46-52 and his own listing of villages whose speech was intelligible versus unintelligible to him matched the Tagoi/Tegali speaking villages listed by Stevenson perfectly. Based on this information, Tingal should be considered a Tegali dialect [ras]. See also: Tegali [ras].
Retired in ISO 639-3: merge into Tegali [ras]
Excerpt from change request document:
The original classification of Tingal as a separate language was based on a misreading of the only published reference to it.
A field check has established that Tingal is a dialect of Tegali [ras].
The Ethnologue entry for Tingal appears to be based solely on Tucker & Bryan, 1956, p.70, "The speech of Tingal or Kajakja is reported to be different from that of Tegali and Rashad; it is uncertain whether it belongs to the Tegali or Tagoi Cluster. Population 520". This in turn would seem to be quoting almost directly from Stevenson, 1956/7, p.103, "The dialect of Tingal or Kajakja (Kajaja) (520 TP) is orally reported to be 'different from Tegali and Rashad' but it is uncertain whether it belongs to this cluster or to that of Tagoi." This does not establish Tingal as a language separate from Tegali [ras] and Tagoi [tag], and it was only based on hearsay.
