the american way to spell my name is chervenka. i figured out in czech that its spelling would be cervenka. but my grandpa said that the original spelling was czervenka, so what is its origin? i was lookign up other slavic langauges and im thinkign maybe its polish? what do you people think?
It's very common Slavic name derived from "červ" (= worm) or more likely from "červený" (= red <- dyed by worm). The most common Czech variants are "Červenka/Červenková" (male/female) and "Červinka/Červinková". As for the orthography, "cz" is either the old Czech way of writing "č", or the recent Polish way, or a foreign (German, English...) transcription. I don't think your name is Polish, since Poles use "w" instead of "v". Most likely it is Czech or Slovak.
In English, that's a robin - used extensively on Christmas cards. Also known affectionately as robin redbreast!
