adjectives - What is the difference between "phonetic" and "phonemic"?


I've read several descriptions but I still don't understand. From what I can gather, the main (or only) difference is phonemics is not concerned with "nondistinctive elements" but I don't know what that is.


Also, is there such a thing as a "phonemic transcription" (as opposed to "phonetic transcription")?



Answer



Phonemics, or Phonology, is the study of the distribution of sound systems in human languages. A Phoneme is a particular set of sounds produced in a particular language and distinguishable by native speakers of that language from other (sets of) sounds in that language. That's what "distinctive" means -- the English phonemes /n/ and /ŋ/ can be told apart by native speakers of English, because we use these sounds to distinguish different words -- sin ~ sing, ton ~ tongue, run ~ rung, etc. This would be impossible if these phonemes weren't distinctive in English.


Phonetics, on the other hand, is simply the physiological and acoustic study of speech sounds, covering all sounds used in all languages, and relying only on the physical and physiological characteristics of the sounds, without regard to their systemic patterns in various languages.


Phonemes, the unit of (this variety of) phonemics, encased in /slashes/, are always specific to a language. Since phonetics is a natural science, phones, the unit of phonetics, encased in [square brackets], are universal, and are not specific to any language.


Thus, we say that there is such a thing as "the phone [p]", because phones are defined universally, but that there is no such thing as "the phoneme /p/", because phonemes are relative to languages. Thus "the French phoneme /p/" and "the English phoneme /p/" both exist and are meaningful, and the phone [p] is represented in both of them; but they are not the same sets of sounds and they don't have the same distribution, and thus are not the same phonemes.


Edit: The set of American English phonemes (from Kenyon and Knott) is available here.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
