Should the word
therefore be separated from the sentence by commas in this sentence?
The fish was fresh and, therefore, satisfactory.
I feel it is restrictive and therefore
doesn't need commas because if you take out the word 'therefore' it implies that it is read like this: The fish was fresh and satisfactory.
It no longer states that the fish was satisfactory
because the fish was fresh as it now states that is fresh
and satisfactory- suggesting it is satisfactory but not because it was fresh.
So, is it correct to leave out the commas for my above reason?
Second example,
The striker can pass the ball out wide to perform a move, for example a cut.
Is it correct to have just the one comma before the word for? I feel that
for example a cut is parenthetical information. I initially thought that a comma should go after example, too. But then it would mean that for example in non essential and could be left out of the sentence, but that would not make sense:
the striker can pass the ball out wide to perform a move a cut.
Therefore, I feel the whole bit is parenthetical:
for example a cut and not just for example. So how I have written it is correct, correct?
Is this all the correct reasoning?
Thanks
