Ĉu vi volas diri "Kiel oni prononcas 'ktp'?"?
Mi aŭdis kaj "kaj tiel plu" kaj "ko to po". (In the second case, the accent is usually on the last 'word', which is why I spelled it as "ko to po" rather than "kotopo" which would be interpreted as "kotópo" rather than "kotopó".)
A lot of abbreviations in English internet slang often get pronounced as they are written, though.
LOL - el-oh-el
BRB - bee-are-bee
FYI - eff-why-eye
IRL - eye-are-el
OMG - oh-em-gee
And of course there's ETA (ee-tee-ay) and ASAP (ay-sap) in standard English. I don't even know what ETA stands for, but the T probably stands for time?
(* internet research * ah, Estimated Time of Arrival, apparently)
@RaizinM : and people get into big arguments about the pronunciation of "GIF" (which the creator, wrongly, expects to be pronounced as if it's "jraphic" [i-something] [file or format f-something]). "Lol" could become an acronym, where the abbreviation is pronounced as a word (e.g., radar, scuba, laser, ASAP), but the others only work as initialisms, pronounced as spelled-out letters, such as FBI, KGB, MD. Someone, somewhere, has probably written a paper on why CIA & IRS have never switched from initialisms to words while NASA, NAFTA, HUD and PIN ("PIN number"!) long ago did so.
Let me quickly weigh in on the GIF debate a bit:
Every argument people use in favor of a certain pronunciation of GIF is wrong, as Idea Channel aptly explained in this video.
- The "it's not Jraphics Interchange Format" argument does not work, as Mizinamo already explained in a reply to your comment, and you admitted in reply to him.
- The "but gin is with a J sound" or "it's obviously pronounced like in gift" argument does not work, because there are plenty words that start with "gi" to support either of the two pronunciations. Gin vs. gift, giant vs. girl, giraffe vs. gismo, etc, etc.
- The "the creator said it's jif" argument does not work, because, as any dictionary editor will tell you, no single person or organization gets to decide how to pronounce words in the English language. Not even the creators of the word. There are plenty words in English that we now all pronounce differently than the person who coined the word. Like a couple hundred of the words invented by Shakespeare.
Linguistically speaking both pronunciations are equally correct. Since it's a modern acronym it doesn't have any word root or history to fall on, and the English spelling rules have too many convoluted twists, turns and exceptions to objectively say from the spelling which of the two is correct. Meaning the pronunciation is almost entirely determined by how people say it. Until either pronunciation is rarely used anymore, both are correct.
The pronunciation of letters in acronyms need not have anything to do with the pronunciations of the letters in the words they came from.
If people say 'jif', it's because of that 'g' often does in English before 'i' (register, gigantic, ....), regardless of how the 'g' is pronounced in 'graphic'.
Compare 'Unicef' (which is not 'younicheff' even though 'c' comes from 'children') or 'laser' which is not 'lazzer' even though 'a' comes from 'amplification' and not 'aymplification') or 'PIN' which is not 'pine' even though the 'i' is from 'identification'.
Or "and so forth" or "and so on", which are also literal translations of "kaj tiel plu". And the literal meaning of the French "et ainsi de suite" comes very close, too.
But I think you're right in that the Esperanto expression was quite possibly originally translated from the German expression. Out of the main languages that influenced Esperanto vocabulary (French, German, Latin, and a dash of English), German comes closest in literal meaning.
Yeah, k.s. has a lot of overlap in meaning with ktp. But I guess you can only use k.s. in an unordered list. Because "and similar" doesn't work in ordered lists, like if you say "the letters of the English alphabet are A, B, C, D, E, and similar" or "the table of four is 4, 8, 12, 16, 20, and similar." You need an "and so on" there.
