I ran into the following sentence:

> **三角や四角** でしか表現できない感情の発露は、ただ恐ろしく。

The same phrase appears in another sentence in the same book:

> 女の子の隣にいることで、ざわめくものがある。拾いあげることのできないそれは、砂浜に広がる波の音に少し似ている。不明瞭な音は **三角や四角**
> の文字以外の形で、わたしにそれを伝えようとする。滾{たぎ}る熱の中に溶けていくそれの答えは、見つからない。

Does 三角や四角 have some special meaning besides "triangle and square"? It doesn't
make sense to me with the literal meaning.

question
phrases
What does 三角や四角 mean in this sentence?
I have not heard of other meanings, but as symbols like triangle are sometimes
used to refer to e.g. words / parts of a sentence when eg explaining grammar,
maybe the sentence was taken out from such a contect, and it was preceeded by
the actual sentence?

I think it is referring to the practice of expressing unintelligible speech in
novels or manga with a sequence of random-looking characters like

△◇ ★彡◼️◇ ¤♡☆_♫ etc.

So, basically, something which cannot be expressed by words but possibly by
some symbols/images.

I have not read the story, but apparently the character pictures emotions as
squares, triangles and circles. I got that from a comment found
[here](https://bookmeter.com/books/13207899/reviews), which says

>
> よかった(語彙力)。たしかに、Amaz○nのレビューにあるように、なぜ沙弥香が女の子にしか恋ができないかを描いているわけではない。内容紹介にもあるように、沙弥香自身の納得のためにこの物語は存在する。ならば描かれるのは沙弥香の“好き”のきっかけだろう。そもそも
> **三角や四角、丸で表される感情** に理由をつけるなんて無粋なのである。

So as long as the person who wrote this comment is not making things up or
just completely wrong, it is an expression unique to the story that only
people who have read it could possibly understand.

Applying it to the second excerpt:

>
> 女の子の隣にいることで、ざわめくものがある。拾いあげることのできないそれは、砂浜に広がる波の音に少し似ている。不明瞭な音は三角や四角の文字以外の形で、わたしにそれを伝えようとする。

When the character is sitting next to a girl she gets a feeling she can't
quite pin down, she compares it to the sound of the waves at the seashore and
that unclear sound is trying to convey a feeling to her that is something
other than (what she understands as) a triangle or square.

I realize a single comment is pretty feeble evidence, but it seemed plausible
enough to post an answer.
