HSK 4 grammar · conjunction
然而
然而 — however / nevertheless
Pattern
opening a new sentence
+
( ) can be left out · other words may come before, between and after
How it works
然而 opens a clause that turns against the previous one — "however", "nevertheless". It is a formal, written connective standing at the start of the second clause, stronger and more literary than 但是.
