At first glance it seems like "Did they stole the bike?" doesn't sound right.
I was going to correct that user and tell him it's steal.
However, when I look up the word stole, it's labeled as past tense.
It sounds funny to say "Did they stole the bike?", but what really is the difference between steal and stole?
Because when saying "Did they", that's inferring the past, right? So would stole actually work as it's past tense, but just sound funny?
