This is the 14172nd most frequent German word.
gleichwohl
"gleichwohl" means "nevertheless" or "however."
Here, 'gleichwohl' is used as a conjunction to express a contrast, similar to 'yet' or 'nevertheless' in English.
Ich war müde, gleichwohl arbeitete ich weiter.
I was tired, yet I continued to work.
'Gleichwohl' is utilized to show that the second action contrasts with the expectation from the first condition.
Das Wetter war kalt und windig, gleichwohl gingen wir spazieren.
The weather was cold and windy; nevertheless, we went for a walk.
In this sentence, 'gleichwohl' connects two clauses to indicate that despite the first condition, the second condition is also true.
