lasters

Lasters is the plural of laster, a rarely used English noun with historical and dialect usage. In these contexts, a laster denotes a plasterer—the person who applies plaster to walls and ceilings. The term appears in older construction manuals, trade glossaries, and regional dialect dictionaries. In modern English, laster is largely replaced by plasterer and is seldom used outside historical writing.

Beyond the plasterer sense, there are no widely accepted, specialized definitions of laster in current technical language. Some obscure or historical sources describe laster as a tool or device related to applying or shaping plaster, or as a term for certain plastering processes, but these senses are not standard in contemporary usage and lack consistent documentation. The word can also appear as a surname and may occur in place-names or historical records, where it functions as a designation rather than a term with independent meaning.

Disambiguation typically relies on context: in discussions of building trades or wall finishing, laster most likely refers to the plasterer; in historical or dialect-focused texts, the same meaning is often implied. In modern references, the term is primarily of linguistic or historical interest rather than practical use.
