question:
E.g. is short for exempli gratia, and is in common use to introduce an example within a sentence. Submit a sample of academic writing, e.g., a dissertation chapter. However, some authors use ex. or ex: (short for 'example') for the same purpose, and this form is listed in some authorities like the Wiktionary. Submit a sample of academic writing, ex: a dissertation chapter. I know they both roughly mean 'example', but which one should I use, and when? Are there connotations associated with one or the other? This question has been asked elsewhere, and this very answer comes up when you ask Google about the difference. It would be good to get an EL&U answer for it.
answer:
E.g. is short for exempli gratia and stands for 'for example'. Ex., if used to mean the same, is incorrect. Mostly ex. is used as short for exercise and not 'for example'.


question:
Are there programmers here? I'd like to know how you guys pronounce cURL. Because I don't live in a country that uses English, I haven't heard it yet.
answer:
According to the authors of the library, We pronounce curl and cURL with an initial k sound: [kurl]. This same FAQ notes that one of the reasons for which the name was chosen was '[t]he fact it can also be pronounced 'see URL'', an obvious pun on the use of the library, which as you know is to retrieve web resources. For what it's worth, I always pronounce it with the initial k sound, as in the English word 'curl.'


question:
Is there a specific reason for this? After all, it is 'boys and girls', rather than 'girls and boys'. If the boy (male) comes first here, why doesn't it come first in 'ladies and gentlemen'?.
answer:

It probably has to do with the phonetic and metrical properties of 'ladies and gentlemen' versus 'gentlemen and ladies.' Say them both out loud and see which one sounds better to you, intuitively. The metrical pattern of 'ladies and gentlemen' consists of (arguably) two dactyls. A dactyl is a group of three syllables where the first is stressed and the second two are unstressed. When these occur in succession, they are pleasant to the ear. ladies and gentlemen DUM da da / DUM da da The metrical pattern of 'gentlemen and ladies' falls into a much less regular pattern. It is less pleasant to the ear. It is something like a stressed syllable followed by three unstressed syllables followed by a stressed syllable followed by an unstressed syllable. gentlemen and ladies DUM da da da DUM da Our language tends to organize itself according to regular and pleasant stress patterns. My guess is that is why we feel more drawn to 'ladies and gentlemen' than 'gentlemen and ladies' and why the former has conventionalized.
