I saw a sentence on English Language and Usage SE that goes:
This is probably borderline archaic or dialect-dependent, however, but other terms are that as well: maid, maiden, lassie, colleen, etc. (From Robusto's answer)
This sentence sounds somewhat awkward to me. My understanding is that "however" and "but" are almost the same word ("however" being formal and "but" being informal), although I'm not very sure about the above construction. Do "however" and "but" have different meanings in the above sentence? In what situations can I use them like that?
