In a situation of learning steps that need pre-skills in order to learn following skills, for instance, I must learn A first then I can learn B.

From above situation, I could say,

B require A.

I know this would be fairy easy to use passive voice (A required by B), but I still wonder is there any verb to describe the above situation,

A ???? B.

    B requires A, with -s, and A is required by B. – StoneyB on hiatus Feb 16 '14 at 23:31

In my opinion, it is better to say Learning B requires learning A or A is a prerequisite for learning B.

However, it's understandable why you'd want to say "A something? B". If you're looking for something short and easy to remember, perhaps simple words like before and then could work, e.g.

(You need to learn) A before B.

If a single word is not a must, and rephrasing is allowed, prepare or ready could work too, e.g.

(Learning) A prepares you for (learning) B.

As a side note, there are a few verbs which might work, but they all sound very awkward to me: forerun, forebode, designate. For example, "A foreruns B" might work, but rather awkwardly.

  • Don't you mean "learning B requires learning A"? – Peter Shor May 11 '14 at 3:26
  • @PeterShor Yes, it should be as you commented indeed. I wonder why I couldn't catch the mistake even after I've read my own answer several times. Thank you! – Damkerng T. May 11 '14 at 5:23
