Practically the whole of the population of this area, with the exception of an enclave of Nahua-speakers in southern Guatemala, spoke dialects of the language known as Maya in the broadest sense, to which the tongues of the Huaxtec and Totonac also belonged. The distribution of the various tribes is best seen from the accompanying map, after Thomas (Fig. 45), but it is hardly necessary to discuss them in detail, since their present positions cannot be taken necessarily as affording any indication of their positions in pre-Spanish times, and from only a very few have legends been collected which shed any light upon their former history. The dialect spoken in Yucatan is known as Maya in the narrower sense, and seems to bear a nearer relation to that which prevailed among the nations of the older culture, since the Yucatec at the conquest were using a script which corresponded closely with that found upon the monuments. Their dialect extends to the Rio de la Pasion and the western and southern Usumacinta, where it is spoken by the so-called Lacandons who have preserved certain of the ancient customs and beliefs. The Lacandons to the west speak the Chol dialect, though there are indications that both divisions of this people originally spoke Maya, that is to say the dialect of Yucatan. Besides the Yucatec, practically the only tribes of historical importance are grouped around lake Atitlan; the Quiché occupying the largest area to the north, south and west of the lake, extending from the Pacific to central Guatemala, the Kakchiquel to the west and south of the lake, also extending to the Pacific, and the Tzutuhil wedged in between them on the southern shore of Atitlan. South-east of the Kakchiquel are the Pipil, a Nahua-speaking tribe, and Nahua dialects are found in San Salvador and even further to the south-east, as far as Nicaragua and Panama, pointing to a stream of Nahua migration by an overland route. The Pipil themselves preserved a tradition that they had reached their present abode from Tuxtla. The Maya language as a whole exhibits certain points of similarity to that of the Mixtec and Zapotec, but its structure is more akin to that spoken on the islands of the Mexican Gulf and the northern coast of South America. A tradition existed in Yucatan that an early section of the inhabitants had come from the east, and the Maya of this neighbourhood were certainly good seamen, since large canoes with sails were met by the expedition of Columbus, so it is at least possible that a section of the early population were immigrants from the Antilles. But at present too little is known of the languages of Central America to admit of the formulation of definite theories based upon linguistic arguments, which constitute a class of evidence requiring extreme caution on the part of those who would make use of it.
