en tjej or en flicka?
I was asking me a question today.
What's the difference between "en tjej" and "en flicka"?
In general they are pretty synonymous and both mean a girl. However, "tjej" has come to be used a lot more generally, so if a female sports team pep talk they might say "Kom igen tjejer!" (Come on girls!). On the other hand male sports team might say "Kom igen gubbar! (Come on old men!).
In addition, tjej can usually be used amongst friends regardless of age. For instance, my great aunt and her three sisters had a tjejträff (literally "girl-meeting", idiomatically "girl's night") a few years ago. The average age was 93.
The team example was to show the wider use of "tjej" (and of gubbe), compared to what one might expect from just "girl" (or "old man"). There are many cases where "tjej" can be used, but where "flicka"/"flickor" would sound weird (such as on the football pitch or when devalanteriels' aunt meet her friends). For sure the male counterpart of girl is boy and hence kille in Swedish.
My Swedish teacher told me that Tjej and Killie mean an older girl or boy, whereas Flicka or Pojke tend to mean younger (like pre teen)
That's frequently the case, but by no means a rule. Most Swedes will use tjej and kille for their children even as infants.
Yes, that is the most typical usage. But while 'pojke' and 'flicka' only are used for children, 'tjej' and 'kille' are not as limited.
I'd say 'tjej' and 'kille' are used frequently from age 0 to 25. For adults they're only used in special expressions, or when you want to compliment someone for being youthful.
