Hello all! I think it is very important to use the term "english" as only on the horizontal axis and draw and follow as a low and high hit. I have taught many newbies the basics of cue ball control and firmly make this distinction every time. The main reason I make this distinction clear is that the reaction of a left of center hit is dramatically different than an above center hit. I always also make it clear that many people (incorrectly) refer to all spin as "english, to avoid confusion for them at a later time.
When you hit left or right of center, the cueball will deflect( squirt) off the line of aim opposite of the side of which you are cueing. Also if the cue is elevated ( which it is on every shot, even if just a little) the cueball will swerve back a bit when the english takes over from the initial impact ( a slight masse action). And once the cue ball arrives at the object ball if it still has sidespin that has not worn off by the friction of the cloth, it will throw the object ball offline from where the contact point would suggest. All of these factors must be considered when aiming a shot with a left or right of hit on the cue ball. Most people just miss enough times and correct their aim accordingly to compensate, but when teaching the theory it needs to be mentioned and defined clearly. None of this occurs on a strict low or high hit on the cue ball. That is why there needs to be a very clear distinction of these two categories of spin, especially in the learning stages. This is why a beginner will become proficient at pocketing balls consistantly, and have to relearn it when they incorporate position ( ENGLISH) in to their game. They have to learn how to aim ( compensate) all over again. Robert Byrne, one of the best pool instructional authors ever, also makes this clear distinction.
Again, among experienced players, it is probably not as critical, because you already are aware of what is going on. However, I think it would probably help cause less confusion across the board if everyone could be conscious of this often misused terminology.
