Welsh bluegrass
Like many of the Celtic languages, Welsh uses the same term to describe both blue and some fresh, natural shades of green. In modern Welsh, we usually use gwyrdd to describe all shades of green, but older Welsh used glas to describe the colour of grass and vegetation. This is reflected in words such as glaswellt ("grass"), which literally means green grass. You'll still find glas used to mean green in literary Welsh and in some fixed phrases (see below for some examples). Just as English uses green metaphorically for people who are inexperienced, Welsh has traditionally used glas in the same way: new students at a university are called glas fyfyrwyr, literally green students.
