What is 'es' doing in this sentence?
why can't "magst du spazieren" be correct?
I am wondering the same thing.
To be clumsy about it: spazieren is weird. It is apparently very odd to use it without gehen. I recall (but can't find) some very detailed discussions about it.
I'm wondering why the verb gehen is used instead of machen.
"Magst du es--" "Do you like it--" "spazieren zu gehen" "--to go for a walk?"
