DYNAMIC DUOS IV

Stephen Sniderman

The same two consecutive letters can be inserted somewhere within each word in the pairs below to form two new words. For example, given the two clue pairs

MAIN     ALLEY
THEY     STAGE

the consecutive letters RG could be added to MAIN and ALLEY, forming MARGIN and ALLERGY.
Likewise, the consecutive letters OR could be added to THEY and STAGE to form THEORY and STORAGE. The duos are never added at the beginning or end of words.

As a solving aid, each letter duo shares one missing letter with the duo from the preceding pair of words, and the other missing letter with the next duo. In the example above, the letter R from the first pair is used in the second pair. The letter O in the second pair will be used in the third pair, and so on. This holds true for the first and last words in each set, which also share a letter. This allows you to solve from the bottom up as well as from the top down. For example, the duo form the last pair in Set I, MANTA and FORT, must contain either an R or a G.
