I am trying to understand how to correctly apply punctuations to complex sentences.

Sentence example:

Learned activities A, B, C, D, E using tools F, G, H, I, J and documents K, L, M, N, O, P, R.

Having the sentence above, what punctuation should be applied to the words [activities, tools, documents] that go before enumerating words [A, B, C, D, E ; F, G, H, I, J ; K, L, M, N, O, P, R] ?

  • Your example is not a complete sentence.

  • Is it because of pattern A,B,C.. words ? Can punctuation change if you put various pattern words ?

  • You need a subject, as James K's answer points out.

Just use commas or nothing if not too confusing:

I have learned activites A,B, and C using tools M,N and O and tools X,Y and Z.

You could put a comma after C and O

Probably rephrase: If this was a real example, from a resume or similar and the activities, tools and documents were more than one letter long, the expression would be over-long and hard to follow. You should probably use bulleted lists

Activites I have learned:

  • A
  • B
  • C

Tools used

  • E
  • F

Or some similar typographical device.
