Nicaraguan Sign Language is a unique language, created by school children in the late 1970s and early 1980s, who previously had minimal success at being taught to lip-read and speak Spanish. This community has been studied as an example of the birth of a language from its beginning (PDF). A recent study has investigated the ability for those who speak Nicaraguan Sign Language to express exact, large numbers. Unlike the Pirahã people of the Amazon (previously) who may not have the need for specificity in large numbers, the deaf in Nicaragua are surrounded by a culture that interacts in specific numbers, yet it appears they lack accuracy with numbers higher than three or four.

It includes specialized dictionaries of religious signs, conversational phrases, and ASL for babies. Unfortunately it's not possible to link to specific signs, but if you look inside you'll find words from "Abbreviate" to "Zoom" and phrases such as "I cannot fasten my belt," "has he been neutered?" "I already took a bath," "are you married?" and "I need a better firewall."

Experts Study New Sign Language System A new system of sign language developed by deaf children in Nicaragua may hold clues about the evolution of languages. When the country's first school for the deaf was established in 1977, children were not taught sign language but developed a system of signs to communicate. Childhood learning may determine linguistic rules ...They found that older students used hand signals resembling the gestures employed by hearing people, mimicking the entire event physically. But younger pupils - who had interacted with other deaf children from an early age - used a more complex series of signs. They split the scene into component parts and arranged these sequentially to convey the incident. The constructions resemble the way words and sentences are built in verbal languages, using segments structured in a linear fashion. This indicates that way the younger children learnt the sign language helped reshape it according to these linguistic rules.

Baby Sign Language. Hearing children can learn to sign before they can talk. Parents can use ASL, or make up their own language.
