Pronunciation: [d͡ʒˈɛst͡ʃə lˈaŋɡwɪd͡ʒ] (IPA) 
The proper spelling of the term "gesture language" can be confusing due to the sound of the "t" and "u" in "gesture." The word is spelled /ˈdʒɛstʃər ˈlæŋɡwɪdʒ/ in IPA phonetic transcription, with the "g" and "s" sounds at the beginning, then the "t" and "u" sounds in the second syllable. This term refers to any non-verbal form of communication using physical movements, such as sign language or body language.
Gesture language refers to a form of communication that primarily relies on bodily movements and nonverbal cues to convey meaning. Also known as sign language or manual language, gesture language is used by individuals who are deaf or have hearing impairments as their primary means of expression. It encompasses a wide range of movements, including hand gestures, facial expressions, body postures, and head movements, which are used to represent words, phrases, and concepts.
Gesture language is not universal and can differ across cultures, regions, and even within specific deaf communities. It is a visual-spatial language that relies on sight, and its grammar and structure can vary significantly from spoken languages. The vocabulary of gesture language may be composed of individual signs (gestures representing specific words or concepts) or the combination of multiple signs to form more complex ideas.
This form of communication plays a crucial role in fostering inclusivity and facilitating effective communication between deaf individuals and those who can hear. It allows deaf people to express themselves, engage in conversations, and participate in various social and professional interactions. Moreover, gesture language also offers a linguistic identity and cultural expression for the deaf community, giving them a sense of belonging and fostering cultural diversity.
In recent times, technological advancements have led to the development of video-based gesture recognition systems, which aim to translate gesture language into written or spoken language using artificial intelligence and machine learning techniques. Such applications have expanded the accessibility of gesture language to a wider audience and improved communication between deaf and hearing individuals.
The term "gesture language" is composed of two words: "gesture" and "language".
The word "gesture" comes from the Latin word "gestura", which means "action, behavior, or bearing". It entered the English language around the 15th century, referring to bodily actions or movements that convey meaning, often used to express emotions or intentions.
The word "language" has its roots in the Anglo-Norman and Old French language, derived from the Latin word "lingua", meaning "tongue" or "speech". It has been used since the 13th century to denote human communication through a system of words, symbols, or signs.
Therefore, the term "gesture language" refers to a form of communication that relies on bodily actions, movements, and expressions to convey meaning, often used by individuals who are deaf or hard of hearing.
