I was trying to find a suitable word for an alphametic puzzle “two+two= …”, suitable meaning guaranteeing a unique solution, and chosen from a database of non-esoteric words. The resulting list of candidate “sums” was eight 3-letter words and sixty 4-letter words.

The overwhelming majority of those 60 (let’s call it set60) lead to the same solution i.e. 720+720=1440, structured as CVVC, VV 2 identical vowels, and CC two distinct consonants, excluding T & W, like book, room etc.

There were very few, still in set60, offering other structures, other numerical answers.

The one you are asked to find is a synonym of another, but the structure is of two equal consonants and two distinct vowels in some order.

Find this word and solve the alphametic.
1. You don’t need an extended data base.
2. No tricks- the 4 letter word is not in the above text!
