# Find the rule to be part of the set

I'll give you a set of words:

{ Achieve, Dog, Cool, Report, Take }

Now if I tell you that Pay can also be in this set, can you find the rule allowing a word to be part of this set?

## 1 Answer

All words in the set can be

prefixed with 'under': underachieve, undercool, underdog, underpay, underreport, undertake.

As requested by the OP: how did I find it?

Being a 'word' riddle, I tried to find words to put before and after your set of words. I stumbled upon 'under' rather quickly, but that might be a coincidence.

• So fast. Can I ask you how did you find so quickly? I'm not an english speaker so maybe it has something to do with it? – IAmInPLS Jul 21 '16 at 14:44
• I'm not a native English speaker either ... I have put my train of thoughts into the spoiler in the answer :) – Glorfindel Jul 21 '16 at 14:56
• Alright, good to know. Good job anyway :) – IAmInPLS Jul 21 '16 at 14:57
