Is 'successfully' redundant and comma OK?

Not really. What if the baby was dead? That's not a success. What if it had birth defects or turned out to be the offspring of Yog-Sothoth?

Thanks, Skeleton.

If I successfully delivered a baby', must the baby be normal. Can't the baby have some defects?

What about the second question? 2. Is a dash between 'boy' and 'Eleon' OK or should it be replaced by a comma?

Yeah you're right, I'd still call a living baby a success regardless. Unless of course it was literal hellspawn. No way. Grab the holy water.

I think the dash is fine.

Thanks, Skeleton.

I have reproduced my questions for your easy reference.

On 16 April, I successfully delivered a baby boy – Eleon.

1. Is 'successfully' redundant?
2. Is a dash between 'boy' and 'Eleon' OK or should it be replaced by a comma?

"Successfully" is not out of place but could be redundant unless you wished to draw attention to the fact of the success, e.g. you are not a doctor, you are a recently qualified doctor and it was one of the first deliveries in your medical career, the foetus was at risk in some way, the mother was sick, the pregnancy had not gone full term, etc. This information would be in the surrounding text.

The dash is Ok but could be replaced by a comma or a colon.

Agree most wholeheartedly, depending however on editing requirements in force

a baby boy – Eleon.

Technically the character between 'boy' and 'Eleon' is a hyphen, not a dash.

There are two sorts, an 'em dash', and an 'en dash'. The 'em dash' is the one to use here, and it should have no spacing before or after. A baby boy—Eleon.

Here are a hyphen followed by an em dash - —

Most people seem not to bother, but a dash is usually obtained (on a Windows computer) by:

1. Hold down the Alt key
2. Type 0151 on the numeric keypad
3. Release the Alt key.

In Microsoft Word you can insert it as a symbol. As I said, this is not sometghing that many people bother about, but it is true that a hyphen is not a dash, and vice versa.

Leave it up to Con revealing all technicalities
Indeed "English finance (?) professional"

Well yes tho depends on context but then doesn't everything. Still maybe don't needcomma; as I've said it's on the way out except where needed for meaning

or "baby"

On 15 April I unsuccessfully delivered a dead male dog. "Unsuccessfully,"? you respond; yes, its mom died too. Then...
On 16 April I successfully delivered a baby boy

You do that every time you want to make a dash?

All you have to do is type a word, make a space after it, press down the hyphen key, make another space, type another world, make a space and then you've got an en dash. For the em dash, all you have to do is type a word, immediately type two hyphens, type another word, make a space. then you've got an em dash.

That may be true with some software (are you talking about a word processor?) and even then in MS Word only if you have Autocorrect turned on. I prefer to have full control of what I type.

Oh, I see.

Thanks to all of you.
