2. Sometimes we get double consonants, like <dd>\begin{align*}<\text{dd}>\end{align*}, because of simple addition: When an element that starts with a certain consonant comes right after an element that ends with that same consonant, we get double consonants.

In the twenty words above there are six words that have <dd>\begin{align*}<\text{dd}>\end{align*} because of simple addition. Three of the six are compound words and three of them contain the prefix ad-. Write the six below and analyze them enough to show where the <dd>\begin{align*}<\text{dd}>\end{align*} comes from in each one.

Word Histories. The meanings of pudding and odd have changed greatly over the centuries. Originally a pudding was an animal's stomach, stuffed with seasoned meat and served as a sausage. In the 16th\begin{align*}16^{\text{th}}\end{align*} century pudding referred to any kind of food boiled in a cloth or bag. In the 17th\begin{align*}17^{\text{th}}\end{align*} century it began to be used to refer to the sweetened dessert we eat today. Odd comes from an old Scandinavian word that meant “triangle”. In time it came to mean “third”, because of the number of sides in a triangle. Then it came to mean any odd number — and finally it described anything unusual.
