Nurmenuku (Nurmenukk)
Cowslip, Primula veris, full name harilik nurmenukk, literal translation uncertain: common (yes) meadow (yes) projecting part (sort of, if you look at the flower). Other names, which often sound bizarre but sometimes just reflect a similarity of shape, include kanavarvas (chicken toe), käekaatsad (work trousers made from tow or linen), taevavõti (heavenly key, key to heaven, perhaps reflecting their looking like bloomers and corresponding bliss once opened?), saksapüksid (German, i.e. posh, trousers), kikkapüksi (trousers that stand up on their own? Some Hell’s Angels had a rather unsanitary cultish behavior revolving around this*...), piimapisarad (drops of milk), pääsulill (escape/salvation flower), and even kanaperse (chicken’s arse). As we see, consensus rules. One of the Mähe flower-name group, see Oblika.
* If you’re really desperate to know, it involved urinating on their jeans so often they’d stand up on their own.
