Subj : articles are a good subject To : Anton Shepelev From : alexander koryagin Date : Mon Oct 09 2017 17:53:55 Hi, Anton Shepelev! I read your message from 07.10.2017 15:43 about articles are a good subject. AK>> "In" is IMHO valid when we talk about the period when something to AK>> be done. "I will have finished it in two weeks." AS> Correct, but it is another meaning. "in" is possible in the your AS> original sentence, but I am uncertain whether it is formal or AS> colloquial, AmE or BrE: AS> https://english.stackexchange.com/questions/46519/for-a-long-time-vs-in-a-long-time AS> https://www.usingenglish.com/forum/threads/6324-in-a-long-time-for-a-long-time AS> https://forum.wordreference.com/threads/in-a-long-time-vs-for-a-long-time.2371239/ Well, probably the following answers are the most accurate: -----Beginning of the citation----- I think they're both valid, but for is probably _much more common_, and in seems to me somewhat more dialectal/informal. - or .....they are the same, except in some very special phrases. For example, one can say "I have been sitting here waiting for a long time" but it would be incorrect to say "I have been sitting here waiting in a long time." ----- The end of the citation ----- AK>> [occurred] AS> Thank you. Is it you or your spell checker that notice(s) my AS> orthographical mistakes? If the former then I compliment your AS> observance. I noted it myself when I read your message. But I have a spell checker -- when I answer your message the spell checker marks the spelling errors (both mine and yours) with red. AS>>> Not to mention the difference between "talk of" and "talk about". AK> AK>> "Of" is often used along with "about". In Russian we also have two AK>> similar prepositions: "pro" (of) and "o" (about). AS> Meseems that in English "talk of" refers to a casual, even AS> tangential, meantion whereas "talk about" denotes a more focused AS> discussion. https://www.usingenglish.com/forum/threads/17343-talk-of-talk-about -----Beginning of the citation----- Student: talk of/ talk about Can they be used interchangeably? And whatever the answer may be, does it go the same with learn of/about, tell of/about? English Teacher: Often 'about' implies more detail and 'of' just the basics. With 'talk', I feel the distinction is less clear- sometimes they are used interchangeably. ----- The end of the citation ----- Bye, Anton!
