Write the nouns of the following adjectives as in the examples. Examples: Expensive : Price Deep : Depth a) high b) wide c) thick d) heavy e) fast

The task requires converting the given adjectives into their corresponding nouns, following the pattern shown in the examples. Below are the correct noun forms for each adjective, derived systematically by identifying the suffix or root transformation needed.

### **a) high**

The noun form of *high* is **height**. This follows the common pattern where adjectives ending in *-y* are converted to nouns by replacing *-y* with *-th* or *-ity*. For example, *happy* → *happiness*, *deep* → *depth*.

### **b) wide**

The noun form of *wide* is **width**. This is a regular conversion where the adjective ending in *-e* is transformed by adding *-th* or *-ness*, but in this case, the root *wide* directly becomes *width* (similar to *length*, *breadth*).

### **c) thick**

The noun form of *thick* is **thickness**. Here, the suffix *-ness* is added to the root *thick* to form the noun, following the pattern of adjectives ending in *-ic* or *-ck* (e.g., *thin* → *thinness*, *weak* → *weakness*).

### **d) heavy**

The noun form of *heavy* is **heaviness**. This follows the standard rule where adjectives ending in *-y* are converted to nouns by replacing *-y* with *-iness* (e.g., *happy* → *happiness*, *lazy* → *laziness*).

### **e) fast**

The noun form of *fast* is **speed**. This is an irregular conversion where the adjective *fast* does not follow a standard suffix rule. Instead, it is linked to the noun *speed*, which represents the concept of moving quickly (e.g., *fast car* → *high speed*).
