What's up
The phrase 'Welche Welle' in German is a combination of 'welche' which means 'what' and 'Welle' which means 'wave'. However, this direct translation does not make sense in English. 'Welche Welle' is more likely to be used in a context like 'Which wave is this?' or 'What kind of wave is this?'. Therefore, it's important to understand the context in which the phrase is used to translate it correctly.
Which wave hit you?
This phrase can be used both literally, asking about a physical wave, or figuratively, inquiring about a wave of emotion or a trend.
Which wave are you riding right now?
Often used figuratively, this phrase could be asking about what kind of trend or movement someone is currently part of or interested in.
How big is the which wave?
This phrase could be used in a situation where someone is observing different waves - in the ocean or in a context of trends or movements - and wants to inquire about the size or extent of a specific one.
