| Type | Initialism |
The initialism MS stands for Member of the Senedd in Welsh parliamentary references. The Senedd’s naming announcement gives the Welsh title as Aelod o’r Senedd, abbreviated AS.
The official May 6, 2020 announcement records the adoption of the Senedd name and member title. That naming event does not establish an individual’s present membership or representation area. Keep the person’s name, title and date together in a historical citation, and check current official information before describing a present role. MS is different from the courtesy title Ms. before a name.

Meaning in context
- Member
- The elected-representative role in the title.
- of the Senedd
- The named Welsh parliamentary context; AS is its Welsh-language counterpart.
