EL uses eleven grammar bases:

Among them, six of {ga-gf} are only for grammatical usage;
having one or more grammatical function(s), but not relating to any images/meanings.
The other five: are from ordinary bases;
and each has its image(s) when compounded with another ideogram.
But each basis itself works for one or more grammatical function(s),
ignoring their own images. Smaller shapes were chosen for grammatical bases except verb bases.
Because they work for showing relations between meanings,
and when the sizes are different from other characters,
the structure of a sentence would be caught easily.

Additional mark for Hyphen

gf:
Before was used for "gf" symbolizing compounding, but for more convenience of EL typing,
the shape was renewed into 1/4 width of the frame. The new shape is like hyphen,
because the function is the same to hyphen.
This basis is always in the single form; and works as “bond” between symbols/meanings
to show a C-c without actual compounding.

E.g.
(picture-like ideogram for insect ) is also shown as braking down into its elemental bases.
This way is useful for a beginner to learn fundamental picture-like symbols, or for hand signing and vocal communications.
(cicada) is also shown as (insect)-(tree)
(grasshopper) is also shown as (insect)-(grass)

* In an EL phrase, usually the left character modifies the right one, unless including a grammatical mark
to change that order. But for showing elements of a c-c with the hyphen , the main element
at the head would be more easily understood.

Additional mark for Switching Meaning of a symbol

ga is always compounded with another C-c, to switch the meaning:
from the picture-based meaning to the meaning as the gathering of its element bases.

E.g.
: sprout (picture-like ideogram)
( with ga): artificial/human made( )-plant()

The bases for pause , punctuation and period

01:
Being between characters/phrases/sentences bound by brackets, it punctuates them.
is the base to show the image of dot(s) in a C-c.
A dot can visually and clearly separate characters,
so no necessary to keep a space on the both sides when it works for punctuation.

In continuous ideograms, the front one modifies the next,
but when this basis is between them, both ideograms are just equally listed.

e.g.
  :
That (in the topic) branch, stem and root were parts of one tree.
Perhaps the English translation can be as above, but the nuance is like
“Each of these branch, stem, root was a part of one tree.

: Two or more of this basis shows a pause;
and if the numbers are larger, the pause is subjectively longer.
This ending shows some imagination echoes of the sentence/phrase
or some silence before starting the next sentence.

is also used for forming the heads to get attention, an interrogative,
a request/imperative and an exclamatory sentence; also for the tail of a wondering sentence.
See the Idiomatic expressions section for these usages.

32:
This basis works as a period of a sentence, having an empty space next, in the same way as English.
The basis has the image of a (measuring) unit in a C-c,
so as the single form, it shows the period of a unit of sentence at the end.
also is used for decimal point with numerals.
See the examples of those usages at 32 in the EL dictionary.
