As a matter of practice, larger issuers have since long voluntarily offered more forward-looking information than was strictly required

I'm unfamiliar with the expression "since long".

Could you kindly me let me know what "since long" means?

I guess it would mean something like "since a long time ago".

If it is, is it grammatically correct to say "since long" in that way?

  • Sounds to me like a fluent but non-native speaker making one of the most common mistakes that seem to persist in that group (in my experience of international scientists). It comes from expressions like “seit langem“ in German and “depuis longtemps” in French. – David Jan 5 at 17:36

I refer you to the following passage. As a native British English speaker, using 'since long' in this fashion is perfectly normal. You find it quite often in official documentation and legal speak.

The meaning is as explained below, very much like you said, 'since a long time ago'.

Hope this helps.

    While we are at it... I feel there is a difference between "since long" and "long since". Is it true? – linuxfan says Reinstate Monica Dec 6 '19 at 6:34

    @linuxfansaysReinstateMonica An interesting point, im unable to find any official documentation on the differences, but in general English the two are somewhat interchangeable. You could say, "That car has long since passed its best." As easily as you could say "That car has since long passed its best." Though i feel like the latter would read better with some structure changes. "That car has since long been useful." Though although i have no proof, it feels like "Long Since" has replaced "Since Long" from Old English to new English. – RustyUK Dec 6 '19 at 7:01
  • Maybe I'm wrong, but think at the different sentences; 1: "It's long since I've stopped to drink beer", and 2: "Since long, I've stopped to drink beer". – linuxfan says Reinstate Monica Dec 6 '19 at 7:46

    I disagree. Long since is standard English, but since long is definitely not (though we san say since long before [a particular time or event]. The sentence quoted by the OP contains either a typo or an error. Oh, and @linuxfansaysReinstateMonica, it's I've stopped drinking beer, not to drink. – Kate Bunting Dec 6 '19 at 9:17

    You realize that all examples you gave don't match the question? – Yosef Baskin Dec 17 '19 at 19:44
