What does thatch mean?
Thatch refers to a traditional roofing material made from dried straw, reeds, or other plant material, as well as to a roof covered with it. The word is strongly associated with cottages, barns, and older buildings, especially in rural Britain, where thatched roofs are a familiar part of the architectural landscape, though it is also used in American English. As a verb, thatch means to cover a roof with such material. The term has a practical meaning but also evokes craftsmanship, rural life, and buildings with a distinctly traditional character. A thatch can be treated as the material itself, as a roof covering, or as the process of applying the material. Related forms include the adjective thatched, as in “a thatched cottage,” and the noun thatching for the material or roofing process. While modern construction usually favors more durable manufactured alternatives, thatch remains significant in historic preservation and traditional architecture.
A roof covering made of straw, reeds, or similar plant material; the material used to make such a covering.
"The thatched cottage is a local landmark."
As a mass noun, it refers to the material; as a countable noun, it can refer to an individual roof covering.
To cover a roof or building with straw, reeds, or similar plant material.
"They thatched the roof before the first winter."
This use is less frequent than the noun and is commonly used in descriptions of traditional building and roofing work.
The plural is used for separate roof coverings or distinct masses of thatch.
"The village has several thatches with distinctive ridge patterns."
Thatch turns a roof into both its covering and the act of making that covering: you can admire the thatch, or watch a roof being thatched.

Where does thatch come from?
Thatch comes from Old English þæcce, an inherited Germanic word for a roof covering or roofing material. It belongs to a Proto-Germanic family of words meaning “roof” or “covering” and is cognate with Old Norse þak, Dutch dak, and German Dach. The English word continued into Middle English and developed into its modern form alongside the related forms thatched and thatching.
