What does Thanos mean when he says "This day extracts a heavy toll" upon meeting Doctor Strange on Titan in Avengers: Infinity War? I used Google Translate and it didn't really mean anything in my language.
It was said as part of a sentence:
Thanos: I take it that Maw is dead? This day extracts a heavy toll.
Also, shortly before that scene, Thanos
Has to sacrifice Gamora to get the Soul stone
So the toll is losing people he trusted and cared about a lot.
