of the gray old men (from hall, gray; vana, old; and mees, man)
This word caught my attention while traveling by bus earlier today. It is the name of a small street in Tallinn. Street names are inflected in the genitive or possessive case (mees is the nominative, while mehe is the genitive case for man) The equivalent in English is to say “street of the gray old men“.
As my better half said, just think of Gandalf in Lord of the Rings. Who knows, maybe this is his street.
