I believe that 2 and 3 below are meant to show fingers opening or shutting one at a time. I'd put a slow arc next to them to show that it is happening slowly, not a forward arrow as that implies that the hand (in madrugada) is bending or moving forward and the handshape for the 5 hand. Also, in seeing something like two wedges, I think of a double motion, like the ASL sign for "light" not a gradual and slow opening.

Subject: Re: Opening the knuckles from the hand, one finger at a time

Hello Valerie, Charles, Stefan and everyone,

I know that when the hand is open and closes one finger at a time starting from the pinky finger, I know you can write in two ways:
- Symbol "Opening the knuckles from the hand, one finger at a time" (an arrowhead inside the other) or
- 'Finger trills' (as exemplified Valerie and Charles).

The question is when the hand is closed (closed fist "S") and begins to open one finger at a time starting with the pinky finger. I thought of writing using the "Opening the knuckles from the hand, one finger at a time" (an arrowhead inside the other) near the pinky finger.

See the following two examples:

1 - Madrugada (dawn)

2 - Explicar (explain)
[log in to unmask]" style="border-color:initial;border-color:initial;">

Hello Madson, Charles, Stefan and everyone -

Big smile ;-)

There are two ways to write Finger Trills - both are fine. I personally prefer this one, which shows the progression of one finger closing or opening and then the next and the next and the next - one dot at a time - you start reading at the end of the arrow and move towards the arrowhead direction - These are very detailed symbols:

Studying on "Opening the knuckles from the hand, one finger at a time", found the following:

"The fingers are extended, opening the hand one finger at a time, starting with the index and ending with the little finger. [...] Note: In some languages​​, opening or closing the hand one finger at a time Can start with the pinky or the index / thumb. In some cases it may be
contrastive and you will need to Specify Which finger starts the process "(Parkhurst & Parkhurst. A Cross-Linguistic guide to SignWriting®: a phonetic approach, 2008, p. 70)

In Libras has several signs that this movement begins with the pinky finger. I thought to adopt the following convention: put the symbol "Opening the knuckles from the hand, one finger at a time" near it (pinky finger) so it was clear that the movement starts for him.

See the examples:

Madrugada (Dawn)

Explicar (explain)

What do you think?
