On Christmas Day my Uncle Paul
To look at something came to call
“...!” he shouted. That was all.
For clues that’s not a lot, I know.
Ive got a hunch you’ll guess it though.
What was the one English word that Uncle Paul shouted?
My guess is
Each line begins with the line number spelled out, but missing a letter. Therefore, line three begins with 'three' but missing a letter in the same way. Our options are 'hree', 'tree', 'thee', and 'thre'. The only one that is a real word that someone could conceivably shout (no one shouts 'thee') is the answer.
