When writing the word more hungry the word hungry changes to

hungrier.

The word "hungry" changes to "hungrier" when used to describe that someone or something is even more hungry than before. This is the comparative form of the word "hungry."

To change the word "hungry" to its comparative form, you need to add the suffix "-er" to it. The comparative form of "hungry" is "hungrier." This suffix is used to indicate that something has more of a certain quality compared to something else.

In general, when you want to form the comparative degree of an adjective, you can follow these rules:

1. For most adjectives with one syllable (e.g., "big," "small," "fast"), add "-er" to form the comparative degree. For example, "bigger," "smaller," "faster."

2. For adjectives with one syllable that end in a silent vowel followed by a consonant (e.g., "thin," "fat," "dim"), double the final consonant and add "-er." For example, "thinner," "fatter," "dimmer."

3. For adjectives with two or more syllables, use the word "more" before the adjective to form the comparative degree. For example, "more intelligent," "more beautiful."

So, in the case of "hungry," which has two syllables, you use the word "more" before it to form the comparative degree. Thus, "more hungry" is the correct comparative form of the word "hungry."
