Can we say "כתמיד, הוא לבד"? Do you really have to say כמו? I always say כתמיד.
You can, but it sounds unnatural in everyday speech.
Isn't this formal section?
What do you mean?
Is "כתמיד" formal? Because this sentence appeared in formal section.
Yes, it's quite formal.
Shuki, if you encounter this again, report it and I'll add it. Obviously as Amir wrote here before, it's not the most natural expression, but we'll accept.
כתמיד, הוא לבד still not accepted April 2020
הוא לבד, כרגיל
