What's in a Prague street name

Na sponě was built in or before 1941.

‘Spona’ can be translated as clip, fastener, buckle, and so on. It derives from the verb ‘spínat/sepnout’, which translates as ‘to fasten’ or ‘to clip (together)’. So, a ‘tie clip’ would be a ‘spona do kravaty’.

In grammar, a ‘spona’ would be a ‘copula’, i.e. a word linking the subject of the sentence with a predicate. It’s usually a very (for example: in the sentence ‘Krč seems endless’, ‘seems’ is the copula.

A ‘spona’ can also be a ‘fibula’ in the sense of a brooch that was used to hold clothing together (in other words, a safety pin before safety pins were a thing). Whatever the meaning, ‘spona’ is clearly linked to the German ‘Spange’.

And, for reasons which we can only guess at (educated guesses, mind you), the area around here was apparently once known as Spona.
