BROTHER:
This sign starts with either a modified "L" hand or "G" hand
on the dominant hand and an "index finger" on the non-dominant hand.
Then the dominant hand moves downward while changing into an
"index" finger handshape at the end of the sign.
Variation of "brother" using BOY + RIGHT.
Second version of "brother" using BOY + SAME:
Note the initial starting handshape of the right hand in this
version. This is a great "ASL" version of brother:
"Brother in law" Sign one of the versions of brother
then sign "LAW"
Here is way to sign STEP-BROTHER:
Combine the signs for "his-TURN" and BROTHER.
