Which word has the long vowel /a/ sound?

The word "weight" contains a long vowel /a/ sound, represented by the vowel combination "ea." In phonetics, a long vowel sound occurs when the vowel is pronounced the same as the name of the letter itself. In this case, the "ea" in "weight" produces a sound similar to the letter "a" as it is pronounced in the alphabet.

In contrast, the other words do not have the long vowel /a/ sound. "Wet" has a short vowel sound represented by the "e," "rat" has a short /a/ sound, and "cat" also features a short /a/ sound. Understanding vowel sounds and their representations helps in distinguishing between long and short vowel pronunciation.
