The only proper way to pronounce data is the way Captain Jean Luc Picard pronounces it.

Sometimes day-ta, but more often da-tuh, with the first a being pronounced like acrobat, the second as a schwa.

If it’s well structured then day ta. If it’s more raw then dah ta.

Idk why, why the second way sounds more raw.

I had a HS science teachers in the early 90s who was very insistent that, "day-ta is a name, dah-ta is information." And between Star Trek and The Goonies, that made sense to me.

It's regional. I grew up in Australia, where it's pronounced as it is in the US: dah-tah. But I now live in the UK, where it's pronounced day-tah.

The same is true of "router", the network device (but not the woodworking tool): rau-tah vs roo-ter.

Working in IT made it a ballache for a while until I remembered to always change my pronunciation for them. 🙄

It doesn’t matter. Pronounce it either way because it’s acceptable.

Language is fluid and communication is about understanding the intent of what you’re saying. If someone doesn’t know what you mean by pronouncing it either way, then they are being obtuse and need a quick punch in the dongle.

Almost exclusively day-ta.

I'm a day-ta scientist who grabs raw day-ta from a tay-ta warehouse (using an interface that makes it look like a day-ta base) and manipulates it inside day-ta frames in order to do day-ta analysis. I also design day-ta analytics schemas.

Sometimes, though rarely, that day-ta warehouse holds rah dah-ta, though, and I can't tell you how it got there or why.

Non-native English speaker (Brazilian, whose native language is Brazilian Portuguese): sometimes my pronounce of "Data" sounds like the Portuguese word "Data" ("date" as in date of calendar, IPA: /ˈda.tɐ/), but sometimes the "T" sounds like "R", a specific kind of "R" (I have no English examples on mind, but it's a similar R sound as in "Arauto" ("herald") IPA: /aˈɾaw.to/ or Spanish "Toro" ("bull") IPA: /ˈtoɾo/ )), resulting in something like "Dah-rah"

Day-tah.

I hear it pronounced dah-tah more by Brits than Americans

English: /'dɑ:tə/ ['dɑ:tʰə]~['dɑ:ʔə]. The first "a" is the same as in "father".

Italian: /'da.ta/ ['dä:ta]. There's only way to read the word anyway.

Portuguese: I don't use it. There's a native equivalent, "dados" /'da.dos/ ['dä.dos] (dado = a piece of data).

I pronounce it the correct way.

I feel like this thread is missing Australians and Kiwis saying that it's neither /ˈdeɪtə/ nor /ˈdætə/ but actually /ˈdɐːtə/. One of the Australian post docs in the group in which I did my thesis used that last one.

Day-ter

Da-tah.

Day-ta. The latter is how Americans pronounce it?

You’re forgetting the third pronunciation, Dat-uh. “Dat,” as in DAT ASS youknowwhatI’msayin

dətə

IMO The sentence you enter dahta into a daytabase is correct to me. Dahta is like unworked mana (pronounced mahna) whereas manah is what you have done or are doing with it and Tomaytos are fresh, tomahtos are what you have done with them.

People who say potahto should be flogged in the village square however... damn heathens.

Dayta - it comes from the Latin word Datum which is pronounced day tum. At least that's what my middle school science teacher would tell us

"Dah-ta"

I pronounce it both ways. This sometimes strikes people as odd, but I will use both American and British spellings, units of measurement, and pronunciations depending on what I vibe with at the time.

This is entirely different when I'm speaking in Spanish though, as I'll always use Mexican Spanish pronunciations.

Like the A in apple.

I'm always scared of sounding pretentious when I say [d ae dx ax] for some reason, so I generally settle with [d ey dx ax]
