Ok, here is a simple puzzle to think :-
Find the largest lettered word such that deleting one letter at a time can give you a meaningful word in each step .
Note that only deletions are allowed, in each step you can only delete one letter.
Also proper nouns, abbreviations or acronyms, rearrangements of words or anagrams are not allowed.
Each word should be a valid word according to the MW dictionary .
Have Fun. :-)
Bonus :- Find the largest lettered word if deletions and insertions, both are allowed. (You cannot delete and insert alternatively, or you probably have no solutions) .
