gb

hand-sign:
open and extend the index and the middle fingers diagonally toward the outer direction.
(斜め前を向けて人差し指と中指を開く)

name: [de] de sound of den　( デ )

definition (grammar):
To indicate a conjunction, like a comma or and in English by itself (as the single form).
(前の語・語群・文と後ろの語・語群・文をつなぐ)

In English, an empty space is kept after comma. But it's not necessary in EL. The base itself has some empty room, when it works as a comma. Empty space before a conjunction symbol is not necessary, if each of the both sides is a phrase or a bundled sentence with the brackets. It needs a space on the left of the conjunction, when another sentence is following without the brackets. These are not specially set as the rules, but naturally comes out through the general simple rules of EL.
