Will this make us up? I don't know (4)
I believe the answer is:
pass
I believe this is a quadruple definition!!
'will' is the first definition.
(thesaurus)
'this make us' is the second definition.
'pass' can be an answer for 'make' (thesaurus). I'm not certain of the remainder of the definition.
'up?' is the third definition.
(thesaurus)
'i don't know' is the fourth definition.
(e.g. response in a quiz)
Can you help me to learn more?
(Other definitions for pass that I've seen before include "Don't answer a question" , "Pronounce (judgement)" , "Exceed; leave behind" , "degree?" , "Exceed; go by" .)
