7.6: The Diphthong

Difficulty Level: At Grade Created by: CK-12

The Diphthong

The Diphthong [o\dot {\text{u}}]

1. A diphthong runs together two vowel sounds. In the diphthong [o\dot {\text{u}}] the two sounds are [o] and [\dot {\text{u}}]. When we run the two together, we say something that sounds like “ow,” as in cow and cloud and crown. The word diphthong is pronounced [díf-thong]. It combines two Greek elements: di-, which means “two,” and phthong, which means “sound.”

2. In the words below underline the letters that spell the diphthong [o\dot {\text{u}}]:

&\text{account} && \text{ground} && \text{round} && \text{thousand}\\&\text{powerful} && \text{amount} && \text{cloudy} && \text{vowel}\\&\text{mouth} && \text{downtown} && \text{crowded} && \text{mountain}\\&\text{flower} && \text{however} && \text{doubt} && \text{allowance}

3. Now sort these sixteen words into these two groups:

Word Squamble. A Squamble combines a Word Squares with a Word Scramble. Unscramble the sixteen scrambled words below. Then fit them into the rows and columns of the Squares. The number of the scrambled word is the same as the number of the row or column it fits into in the Squares. As you unscramble each word, fit it into the Squares, and that will give you clues about how to unscramble other words. Two other clues: All of the words contain the sound [o\dot {\text{u}}], and in the Squares we have written in the letters that spell the [o\dot {\text{u}}] sound.
