Student or Learner
I have got accidentally through a strange phrase from online youtube: "What is that mean".
This phrase seems to me grammatically incorrect.
For me it's like to mix 2 grammar points: "What is that?" and "What does that mean?".
I am so interested into some native speakers clarifications on this point.
Thanks in advance.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
