Removing unexpected text from a column

Hello,

I have a column which contains a number of different word values that repeat numerous times down the column. 

Sometimes there's instances where the these words have extra text at the end and there's different delimiters used so its hard to predict and therefore I've not used that function. 

Is there a way to just retain the standard word values and delete the extra text without knowing what that extra text will be? It happens across the majority of the different word values too.

So in the below table I'd like to only keep the non-red text. Thanks
