My question is aimed at the constructions of this structure "to go + doing something" which are: to go fishing, to go dancing, to go jogging and so on. I need some explanation about the verb "go" in them. As far as I understand "go" doesn't imply some "moving" on the part of the speaker in such phrases. If I say "I go jogging" it means that "I jog", right? However, I have noticed that native speakers say such things as "I am going jogging now", which basically means " I am leaving right now in order to go jogging." or "I am going to jog." As a result of this I find a few discrepancies.
1) If "I go jogging" = "I jog" then "I am going jogging" should mean "I am jogging (now)." but it means "I am going to go jogging." Is my observation correct?
2) If I say it in the past "I was going jogging yesterday" will it mean that "I was jogging yesterday" or "I was going to go jogging yesterday" or both?
V-ing construction; I had a question (no. 4, pg. 2) about that in my freshman grammar class midterm exam.
