semantic domain or semantic field
What, then, is the difference between a semantic domain and a semantic field? The way they are used here, it's almost as if they are listing them in order to emphasis that they are synonyms ... but I'm not sure.
From the later examples of basketball (https://hyp.is/ynKbXI1BEeuEheME3sLYrQ/en.wikipedia.org/wiki/Semantic_domain) and coffee shop, however, I am pretty certain that semantic domain is quite different from (broader than) semantic field.
For instance English has a domain ‘Rain’, which includes words such as rain, drizzle, downpour, raindrop, puddle.
"rain" seems more like a semantic field — a group of very related or nearly synonymous words — than a semantic field.
Esp. when you consider the later example of basketball (https://hyp.is/ynKbXI1BEeuEheME3sLYrQ/en.wikipedia.org/wiki/Semantic_domain) and coffee shop, which are more like the sense of "field" that means (academic/scientific/etc.) discipline.
For instance, in basketball there are many words that are specific to the sport. Free throw, court, half court, three pointer, and point guard are all terms that are specific to the sport of basketball. These words make very little sense when used outside of the semantic domain of basketball.
But this example seems so different than the first example they gave, "rain", which seems more like a semantic field — a group of very related or nearly synonymous words.
In lexicography a semantic domain or semantic field is defined as "an area of meaning and the words used to talk about it
Semantic domains are the foundational concept for initial stages of vernacular dictionary building projects.
