I figured out the adj question. We were indeed being led astray by the similarity between “adj” and “adv”. We should have been looking at the simlilarity between “adv” and “v”. When we use a regular expression like (adj|v). on the string “quickly, adv.”, we see that the string does contain “v.”. However, the string does not contain ” v.”

    Did you mean to say: the string does contain “v”. However the string does not contain “adj.”?

      No. I meant what I said. Another example:
      echo "quickly, adv." | grep -E '(adj|n|v)\.'
      This matches, which might lead you to believe that that the presence of adj in your regular expression is the reason. However, it is the presence of v

      Compare with:
      echo "quickly, adv." | grep -E ' (adj|n|v)\.'
      This does not match, because we are looking for a space followed by either adj., n., or v.. The space is necessary.

    ah, I didn’t see the space in the last ” v.”
