There's no specific way to *look* at the sound itself. It's an auditory concept, not a visual one. However, we can talk about how the letter e looks in words that have the short e sound:
* e is often followed by a consonant and then another consonant. This is called a closed syllable and it's the most common way to make the short e sound. For example: bed, ten, pen.
* e can also be followed by a consonant and then a silent e at the end of the word. This is called an open syllable and it also produces the short e sound. For example: bake, hope, make.
If you're wondering how to write the short e sound, remember that it's usually represented by the letter e in words. However, there are some exceptions. For example, the word "said" has the short e sound but is spelled with an ai.
So, there's no specific visual representation of the short e sound, but it's typically spelled with the letter e in closed or open syllables.
