Similarities:
* Both are visual languages that rely on handshapes, facial expressions, and body movements to convey meaning.
* Both use a system of signs to represent words and concepts.
* Both are used by deaf communities to communicate with each other.
Differences:
1. Structure:
* ASL is a more iconic language, meaning signs often resemble the object or action they represent. It is also more spatial, using the signing space to convey grammatical information.
* LSE is a more abstract language, with signs often being derived from the spoken Spanish language. It relies more on grammatical markers and word order.
2. Vocabulary:
* ASL has its own unique vocabulary that is not directly derived from English.
* LSE shares many signs with spoken Spanish, with some adaptations for visual communication.
3. Grammar:
* ASL uses word order and spatial relationships to convey grammatical information. It has a system of verb inflections, like tense and aspect, which are different from English.
* LSE follows a more Spanish-like grammatical structure, with subject-verb-object word order and use of prepositions and articles.
4. Influence:
* ASL is influenced by French Sign Language and Native American sign languages.
* LSE is influenced by Spanish and other European sign languages.
5. Community:
* ASL is used primarily in the United States and Canada.
* LSE is used primarily in Spain and Latin America.
6. Sign Production:
* ASL often uses a single-hand sign, with the dominant hand performing the majority of the sign.
* LSE often uses two-handed signs, with both hands participating in the sign production.
In summary:
ASL and LSE are two separate and distinct languages with their own unique structures, vocabularies, and grammars. While they share some similarities, they are not mutually intelligible and require separate learning.
