Question: Possible Duplicate: What is the difference between an expression and a phrase? Difference between "phrase" and "idiom" What is the difference between a phrase, an idiom and an expression? I am looking for the context where one is more appropriate than the rest. I've been using idiom and phrase more or less interchangeably.
Answer: This question asks nearly the same thing. This is the difference between an idiom and a phrase: A phrase is "a small group of words standing together as a conceptual unit", while an idiom is "a group of words established by usage as having a meaning not deducible from those of the individual words". So, the difference is that an idiom as an established meaning not directly linked to the individual words. Any idiom is a phrase. As an example, "raining cats and dogs" is both an idiom and a phrase. "A herd of cats" is a phrase but not an idiom. Expression has about the same meaning as phrase, except it is usually used of a phrase which is in common use. So an idiom is a certain sort of expression, which in turn is a subset of phrase: idiom > expression > phrase.

Question: Are shit, shat, and shitted all correct and fine to use as the past tense of shit? After a little bit of searching it seems that they are, with shat being Old English. Is any form more common in British or American English? Erik Kowal claims that shit is mostly American English and shat British English. [M]ost Americans don't change the verb form for the past tense of certain short verbs ending in -it. So fit, spit, shit, slit and pit are thus formed both in the present and the past tense as far as Americans are concerned, whereas people from Britain would almost always use fitted, spat, shat, slitted and pitted for the past tense. What about shitted?
Answer: The OED's etymology for this word is: The form shite represents OE. *scitan, pa. t. *scat, pa. pple. -sciten (in be-sciten), corresponding to OFris. *skita (NFris. skitj, pa. t. skad, pa. pple. skedden), MLG. schiten, Dutch schijten, OHG. scian (MHG. schian, mod.G. scheissen), ONor. skita (MSw. skita, Da. skide), f. OTeut. root skit-. The now more common form shit is influenced by the pa. pple. or the related sb. As far as modern/current forms go, it says that: The present tense is either shit or shite. For the past tense, the OED gives all three of shit, shat, shitted as current. So the answer to your question is yes. For the past participle, the OED provides only shit and shat, with shitten last appearing in the 19th century. That means you won't find any one "correct" answer. Because those variant forms are all used natively by speakers born to the language, all are therefore "correct". Use whatever you please.

Question: What is the meaning of wrt in the following text? I think this is an excellent idea, but I'd like to see this explicitly reframed under the banner of providing Drupal.org data through publicly-accessible APIs. We started kicking off at least one discussion like that wrt Git over, which also led back to "#112805: XML-RPC Interface".
Answer: It's an abbreviation for "with respect to". Edit: regarding the lack of punctuation (thanks for bringing it up, ukayer), that's definitely because of the informal nature of the context. It would be more standard to write it as w.r.t., except that in any context where punctuation matters, you probably shouldn't use this abbreviation in the first place.
