Was wondering about this sentence:
When the guy on the poop deck yelled, "Land!," everbody began to cheer.
Hmmm - the way I was led to understand this, it should actually be:
When the guy on the poop deck yelled 'Land!', everybody began to cheer.
...or:
When the guy on the poop deck yelled, (
"Land!"), everybody began to cheer.
Since you are describing what somebody said, rather than having a character say it directly, it's not dialog - it's a quote. That's why you would use the first example. The second, you are actually having the charater say the word, but it is an aside to the main sentence.
In other words, your sentence, as constructed, really should be: When the guy on the poop deck yelled, everybody cheered.
What he yelled, in context of this sentence, has to be 'shoe-horned' in. Personally, what I would have gone with would be:
"Land!" The man on the poop deck yelled; and everybody cheered.
That's my two cent's worth.
