Here's why:
* Long e sound: Words with a long e sound typically have the letter "e" at the end of the word or have a vowel combination like "ee," "ea," or "ey." Examples include "see," "tree," "meat," "key."
* Short e sound: Words with a short e sound typically have the letter "e" in the middle of the word and are often followed by a consonant. Examples include "bed," "ten," "pen," "sled."
Since "he" has a short e sound, it is not considered a long e word.
