I think we should play with more complicate rule, 1) Second letter should come within 10th letter of previous words first letter, eg. if we count letter towards a or towards z, means previous word start with S which is 19th letter, if we count towards z we not have 10 letters to count so we have no option to count towards a, 10 letter back we found i, so word start should be ti. 2)2 same letter should allow but not together! eg we should not allow word tizzy, tills etc.
My suggestion is not compulsory,but if it like everybody...

If you understand, say "understand". If you don't understand, say "don't understand". But if you understand and say "don't understand". How do I understand that you understand? Understand!
