They love saying delta in my line of work and I just think it is ridiculous. They also use granularity instead of clarity which seems a waste of time and letters.

Performative bollocks 

As per

Sounds cooler. Delta.

Mississippi Difference?

The Nile difference ranks amongst the world’s most fertile farming areas

Jelly beat me to it

Delta, to my mind, means the range/gap between alternatives. Quantification. 

Difference is more qualitative. 

Vive la Delta

everybody loves the Greeks.

god forbid you say that an interest rate went up by 0.5%.  

WASH YOUR MOUTH OUT .  all about the bps.

It makes you sound more scientist.

Reminds me of that time where high Guise used the words "air frame" when talking about planes. 🥸

winners only care about alpha

Heh I heard this for the first time yesterday. Did we get the same email?

This reminded me of the delta P meme.

Do not google the delta P meme. 

Those poor crabs :(.

Yes, they are clanging bells.

To compound their bellendedness, these campanologicalframes are (in my experience) aping the use of the term as it is commonly used in a financial (specifically, derivatives) setting, where it doesn't even mean "difference between".

Reminds me of that time where high Guise used the words "air frame" when talking about planes.

That wasn't high guise or his socks was it? The <transport>frames meme that it spawned is a classic though. 

Airframe was some other armchair general iirc

Also what OP said. 

god forbid you say that an interest rate went up by 0.5%.

TBF, the former is ambiguous, though everyone knows what you mean. Except during the Trussterfvck period maybe: "rates have gone up by 100%"

The wider point about sheep adopting every new corporate w**k speak is always worth a good lol 

Delta usually refers to numbers. 

I know lawyers have a certain aversion to numbers. 

Difference refers to numbers

It's usually said by people who are incompetent with maths or technical subjects in an effort to sound like they are not just waffling aimlessly and flapping their jaws around

I can imagine Laz waiting for the end of a meeting and being 'last to speak' in his pseudo sage way and then just asking at the end

'but...' (dramatic pause) '...what's the delta?'

Then everyone just gets up and walks out and Laz thinks.

'Heh. Pwned them again'

I find Accretive is the most acute sign someone doesn't know what they're talking about.

The Mississippi difference is shining like a national guitar.

"Difference of Venus" just doesn't sound quite right.  

Dr Dre:  What's the Delta?

Flying Difference Airframes. 

cos it sounds cooler

Delta? Foxtrot Oscar

cos it sounds cooler

does it, though? when you get weapons saying things like:

"Well yah, of course I normally travel in First but on British Airways the delta between First and Business is tiny".

off they can fook

It is the sign of the cheddar

BPs

Bee-Pees or Bips? How do u pronounce yours

I follow a lot of options traders on twitter which makes me very smart and now I don't notice the delta between the two words anymore.

Whoops I did it again. 

Theta.

VIX.

Black-Scholes. 

Hans! Bubba! I don't think you are understanding the delta in our position here. 

We take the volatility distribution of how disappointed our client is, run it through a Kalman Filter and you'll find we are really not that far apart, Hans. Considering the delta, Hans. 

Hans? 

Agree with whoever said above that 'difference' can also contain some qualitative evaluation whereas 'delta' is nearly always just quantitative.
