Mostly (2,3,4)
I believe the answer is:
in the main
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">mostly</span>' is the definition.<br/ ><span class="explanation-format__explanation">(both can mean generally)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for in the main that I've seen before include "For the large part" , "Swimming" , "On the whole" , "Where cod and haddock may be found" , "Almost entirely" .)
