Final answer:
In ASL, January, May, and June are abbreviated, with the rest of the months signed through a mixture of fingerspelling and representative movements.
Step-by-step explanation:
In American Sign Language (ASL), three months are typically abbreviated based on English language conventions. These are January, May, and June. January is signed by signing the letter 'J' and then circling it. May is simply signed with the letter 'M,' and June is signed with the letter 'J.' The other months in ASL are generally signed with a combination of fingerspelling the first few letters of the month and a movement or gesture that is representative of that month. For instance, February is often signed by signing 'F-E-B' and then using a movement to represent Valentine's Day or the concept of 'love,' which is associated with that month. The understanding and conventions can vary among ASL communities, so it's always good to learn from native ASL users.
