Cross River languages

The Cross River or Delta–Cross languages are a branch of the Benue–Congo language family spoken in south-easternmost Nigeria, with some speakers in south-westernmost Cameroon. The branch was first formulated by Joseph Greenberg; it is one of the few of his branches of Niger–Congo that has withstood the test of time.
Greenberg's "Cross River" family originally included the Bendi languages"." The Bendi languages were soon seen to be very different and thus were made a separate branch of Cross River, while the other languages were united under the branch "Delta–Cross." However, the inclusion of Bendi in Cross River at all is doubtful, and it has been tentatively reassigned to the Southern Bantoid family, making the terms "Cross River" and "Delta–Cross" now synonymous.

There are four primary branches of Cross River:

Internal classification.
Roger Blench (2008: 4) classifies the Cross River languages as follows.
Although Blench (2004) tentatively included the Bendi languages as possibly being a Cross River outlier branch, the Bendi languages are generally classified as Southern Bantoid.
