1. Used alone when you mean what you are about to say is easily understood or easy for anyone to agree with given the context, or that it is easy to understand or agree with what the person you have been talking to has said given the context. English = 'Well...', 'Well, there you are...', 'Well, there you go...', 'That's all there is to it...', 'That's it...', 'Yeah...', 'Yep...', 'Yep, of course...', and so on.
2. Used alone when you are hesitating, usually because you have not decided what to say next. It also means you don't mind if the person you are talking to interrupts or takes over. English = 'Well...', 'Umm...', 'Err...', and so on.
1. Used as general question sign. The signer is suggesting that one or more questions (who, what, where, why, how, when) could be posed about what has just been said by either the signer or the addressee, depending on the context. For example, “Who would do such a thing...?”, “Why would anyone do that...?”, “Where’s that...?”, “How exactly did that happen...?’, and so on.
1. This sign form and its variants occur very frequently in fluent signing. When they are extremely brief, lasting only micro-seconds, they are barely noticeable and carry very little meaning. However, when they are held for slightly longer (yet even then they can be quite brief), are made with eye-contact with the addressee, with a degree of stress, or with various facial expressions, they do convey the types of meanings described here.
